Simrad SH90 Simrad SH90 Study this chapter to familiarize yourself with the Simrad SH90.
Simrad SH90 Important As with all other advanced instruments, there are a few important things that you must be aware of.
Simrad SH90 Therefore, before you start the manual operation, read carefully through the relevant procedure(s). You will then familiarize yourself with the methods and the safety requirements. The relevant procedures are located in the SH90 Reference Manual. Transducer handling Note All transducers must be handled as delicate items. Any wrongful handling may damage the transducer beyond repair. Do not activate the transducer when it is out of the water.
Simrad SH90 System diagram A standard SH90 system diagram is provided. Interface capabilities, uninterrupted power supplies and power cables are not shown. A Processor Unit B Colour display C Operating Panel D Operating Panel Power Supply E Transceiver Unit F Power Supply Unit G Motor Control Unit H Hull Unit I Transducer The colour display is not included in the standard delivery from Simrad. This is a commercial item that can be purchased locally.
Simrad SH90 System units The Simrad SH90 comprises the following units. Topics • Colour display on page 13 • Processor Unit on page 13 • Operating Panel on page 13 • Operating Panel power supply on page 13 • Transceiver Unit on page 14 • Power Supply Unit on page 14 • Hull Unit on page 14 • Transducer on page 15 Colour display A commercial colour display is used with the Simrad SH90 system. Note that the colour display is not a standard part of the SH90 delivery.
Simrad SH90 Transceiver Unit The SH90 Transceiver Unit is located in the sonar room, close to the Hull Unit. The transceiver performs the transmission and reception control of the 480 transmitters and 480 receiver channels. 16 identical transceiver boards are used. A dedicated power supply is provided to supply the required DC voltages to the transceiver. One Ethernet cable is used for communication with the Processor Unit on the bridge, and a second Ethernet cable is used to control the hull unit.
Simrad SH90 Caution If the transducer hits larger objects or bottom, the transducer shaft may be bent, or - in worst case - it can be broken off. A broken transducer shaft will cause water leakage through the top of the shaft. In such cases, do not raise the transducer shaft to its upper position. To prevent serious damage, you must have a water pump and a warning system in the sonar room.
Simrad SH90 Key functionality The Simrad SH90 offers certain key functions. The basic principles of the Simrad SH90 are unique because of the 480 transmitter and 480 receiver channels with their transducer elements spread around on the cylindrical transducer. The transmission, reception and data processing are under computer control, and the powerful capabilities of the sonar are the results of sophisticated digital signal processing software and state of the art hardware.
Simrad SH90 Combination of omni and vertical slice The combination of the Omni mode and the vertical slice will give an optimal visualization of the catch situation. Multiple frequency operation In addition to the standard 114 kHz frequency, you can select any operational frequency from 111,5 to 115,5 kHz in 0,5 kHz steps. This is a very useful function when it is necessary to suppress interference from other sonars. Stabilization system The Simrad SH90 is provided with a stabilisation system.
Simrad SH90 Note that this filter is built into the software. It is not available as a function you can control on the menu system. Frequency selection The multiple frequency selections can be used for suppression of interference from other sonars. The sound absorption in salt water increases with the frequency, thus giving the lower frequencies a longer detection range.
Simrad SH90 Ping-to-ping filter The Simrad SH90 is equipped with a ping-to-ping filter (PP Filter) to provide a clean and steady presentation by reducing the interference and noise. This filter compares the echoes from a selected amount of transmissions (pings), and an echo has to be present in the selected amount of pings in order to be presented on the display. Note that in rough seas, when the beam easily can miss the target in several pings, the PP Filter must be used with care.

Getting started Getting started This chapter describes how to get started with the basic operation of the Simrad SH90. It contains a brief overview of the basic system operation and procedures. If you are a first time user, we recommend that you read through this chapter while operating the Simrad SH90 so that you can familiarize yourself with the menus, dialog boxes and display presentations.
Simrad SH90 Operating Panel The Operating Panel is the primary means of user interface to access the SH90 functionality. The most frequently used functions are directly available using the designated control buttons on the Operating Panel. You can enter operational commands directly by the push of a button. To use the functions provided by the menu system, use the trackball and Select, View and Object buttons. These three buttons correspond to the three buttons on a standard computer mouse.
Getting started Note Make sure that you have sufficient water below the hull before you lower the SH90 transducer! Procedure 1 Press the Power button on the colour display. 2 Press the Power button on the Operating Panel, and keep it depressed for approximately two seconds. The green lamp on the right side of the button will flash to indicated that the power has been switched on, and that the computer is starting up. After a short period you will see the sonar picture on the display.
Simrad SH90 Powering off the SH90 Purpose This procedure explains how to power off the Simrad SH90. Procedure 1 Press the Up button on the Operating Panel. The green lamp next to the button will flash, and an audible signal indicates that the transducer is hoisted. Up When the upper position has been reached, the lamp will illuminate continuously, the audible signal stops, and the upper button in the Status menu shows Transducer: UP.
Getting started Operating principles The SH90 is operated using the dedicated Operating Panel. An optional mouse (or trackball) can also be connected.
Simrad SH90 6 Observe that a dedicated View shortcut menu opens. Which menu that opens depends on the current presentation mode, and in which display field you the cursor was located when you pressed the View button. View Tip You can open the same View shortcut menu by pressing the Select button twice rapidly. The functions on the View shortcut menu are all related to the visual presentation. 7 Place the cursor in the echo presentation, and press the Object button.
Getting started 3 Position the cursor on the centre of the menu button (C). Observe that the shape of the cursor changes to a “menu” symbol. This means that the applicable parameter dialog will open when you press the Select button. The dialog appears in the lower part of the menu field, and offers an overview of the available options. Click on the middle of the button to open the parameter dialog. Changing a parameter value Purpose B Observe this generic procedure to change a parameter value.
Simrad SH90 6 Move the cursor down to the Close button (D) in the parameter dialog, and press the Select button again. 7 Observe that the parameter dialog closes. Tip In the Simrad SH90, all parameters are stored automatically. This function will cause the SH90 to remember all the selected parameter settings, even when it is switched off. Understanding the menu structure Purpose The menu contains several different buttons, tabs and parameter dialogs.
Getting started 6 7 At the bottom of the menu, observe the Parameter dialog (F). When you click a menu button, the relevant parameter dialog opens at the bottom of the menu. Each parameter dialog holds one or more buttons or menus. To close a parameter dialog, click the Close button. Most dialogs provide a Help button for access to the on-line help. In this example you can see the Status dialog, which is replaced when a parameter dialog is opened.
Simrad SH90 5 Observe that the menu reappears on the selected side (A), and that the remaining echo presentation area is not re-scaled. A (CD015008C) 6 Move the cursor towards the centre of the display, and observe that the temporary menu disappears. 7 On the Operating Panel, press the Menu button one more time, and observe that the menu reappears.
Getting started Starting normal operation Once you have powered up the complete SH90 system, you are ready to start the actual operation. When started up, the SH90 will automatically apply its previous setup parameters. Observe these brief procedures to familiarize yourself with the basic operations with echo presentations and menu operations.
Simrad SH90 Changing the menu language Purpose The menu system on your SH90 sonar is available in several languages. Procedure 1 Click the Display tab to open the menu. 2 On the Display menu, click Language. Use this function to choose the language used on the menu buttons. 3 Click either side of the button to leaf through the options, or the middle of the button to open the parameter dialog.
Getting started Changing the operational range Purpose The range of your SH90 sonar can be set individually for the horizontal and vertical presentations. • The range applied to the horizontal presentation modes can be changed using the Operating Panel or the Range button on the Horizontal menu. • The range applied to the vertical presentation modes can be changed using the Operating Panel or the Range button on the Vertical menu.
Simrad SH90 3 Alternative method: Vertical gain a Click the Vertical tab to open the menu. b On the Vertical menu, click Gain. This parameter is used to control the range of the SH90, that is the distance from the vessel to the outmost edge of the sonar beam. c Click either side of the button to leaf through the options, or the middle of the button to open the parameter dialog.
Getting started 2 Alternative method: Horizontal gain a Click the Horizontal tab to open the menu. b On the Horizontal menu, click Gain. This parameter is used to control the receiver gain, that is how much amplification that is used on the received echoes. c 3 Click either side of the button to leaf through the options, or the middle of the button to open the parameter dialog. Alternative method: Vertical gain a Click the Vertical tab to open the menu. b On the Vertical menu, click Gain.
Simrad SH90 Procedure 1 Operational frequency, horizontal a Click the Horizontal tab to open the menu. b On the Horizontal menu, click Frequency. 2 This parameter is used to control the transmitter and receiver operational frequency. c Click either side of the button to leaf through the options, or the middle of the button to open the parameter dialog. Operational frequency, vertical a Click the Vertical tab to open the menu. b On the Vertical menu, click Frequency.
Getting started the sonar’s maximum range. As show in the menu, the AGC has four different settings. These settings define the difference between the maximum and minimum echo level for the filter to take effect. Note When this parameter is changed on a horizontal menu, the chosen setting is only put to use on the horizontal sonar presentation. If you change the parameter on a vertical menu, it is only applied to the vertical sonar slice presentation.
Simrad SH90 Adjusting the Reverberation Controlled Gain (RCG) Purpose The Reverberation Controlled Gain (RCG) regulates the receiver gain individually for each of the receiving beams. The RCG filter will enhance the visibility of schools, and reduce the reverberation from bottom and surface echoes. Scattered fish can be perceived as reverberation. The RCG function must therefore be used with care if scattered schools are to be detected.
Getting started Note When this parameter is changed on a horizontal menu, the chosen setting is only put to use on the horizontal sonar presentation. If you change the parameter on a vertical menu, it is only applied to the vertical sonar slice presentation. Tip For scattered fish, we suggest that you use the 40 log R setting. For small schools, try 30 log R, for large schools, use 20 log R. If you use 20 log R the bottom will always be presented with the same echo strength.

Basically, three different views are used. • Omni presentation (horizontal) • Vertical slice presentation • Catch data presentation The size of each view can easily be adjusted.
Getting started Procedure 1 Locate the Mode button on the top of each menu. 2 Click Mode to choose presentation mode Bow Up/Vertical. 3 Observe the omni presentation, and compare it with the example provided. This screen capture has been taken from an SX90 sonar working on a Norwegian fishing vessel somewhere in the North Sea. The Bow Up/Vertical mode is used, and several distinctive schools can be seen. A The information in the top left corner shows the current range, gain and tilt settings.
Simrad SH90 D Not all fish schools are interesting for the skipper. The three schools identified are obviously too small. E This is the school of fish that the skipper is interested in. He has placed a target track on it (3P) indicating that this is target no 3, and that this is his priority target. The audio channel (the white line) is automatically placed on this priority target, this allows you see the same school in the vertical slice presentation.
Getting started Investigating the vertical slice presentation Purpose Observe this procedure to familiarize yourself with the vertical slice presentation provided by the SH90. In addition to seeing the target from above, it is also possible to see the target from the side, by using the vertical slice presentation. In this case the beam covers a continuous vertical beam from 0 to -60 degrees in one transmission.
Simrad SH90 This is the same screen capture one more time, but this time with focus on the vertical view in the bottom right corner. Note that the vertical view is made along the white audio line in the omni presentation. A This information at the bottom left corner of the vertical views provides the tilt, distance and depth of the cursor. The information is only valid when the cursor is located within the view. Once you move it outside, any spurious values may be displayed.
Getting started Investigating the catch data presentation Purpose The combination of the Omni mode and the vertical slice will give an optimal visualization of the catch situation. Observe this procedure to familiarize yourself with the catch data presentation provided by the SH90. The Catch Data view is only available in the following presentation modes: • Bow up/Vertical • True motion/Vertical • 270°/Vertical The purpose of this view is to offer information related to the catch phase.
Simrad SH90 This is the same screen capture one more time, but this time with focus on the catch data presentation in the top right corner. A This information at the bottom left corner of the catch data presentation provides data related to the target. You can read its depth, position, movements, area and the estimated volume of fish. The quantity of fish depends on the parameters you have entered in the School dialog on the Setup menu. B This Net state button is only available if you use a purse seine.
Getting started E The information provided at the top of the view depends if you use a trawl or a purse seine. With a purse seine (as shown in the screen capture), the horizontal line at the top of the presentation does not by itself offer any information. However, the digits shown above it are important. • The left digits are a timer. It will measure the time elapsed since you “shot” the purse seine. The timer starts when you click the Net state button to change its status from Ready to Shot.
Simrad SH90 Investigating the common information on the display Purpose Observe this procedure to familiarize yourself with the common information provided at the top of the SH90 presentation. Procedure 1 Locate the Mode button on the top of each menu. 2 Click Mode to choose presentation mode True Motion. 3 Observe the information provided on the top of the presentation. In nearly all presentation modes, the following information is provided. B A E D C F (CD015013A) A Current horizontal gain.
Getting started 2 Press and hold the Select button on the Operating Panel (or the left mouse button) 3 Move the cursor with the Select button depressed. Observe that the boundary line is moved. Release the Select button. Observe that the boundary line has been relocated to the new cursor position. 4 5 Select Adjusting the variable range marker Purpose The Variable Range Marker (VRM) consists of an adjustable range ring with range read-out.
Simrad SH90 Procedure 1 Basic procedure a Observe the Train field on the Operating Panel. It provides two separate buttons to move the bearing line. b 2 3 Press either of the two buttons to change the direction of the bearing line. Alternative method 1 a Place the cursor anywhere on the bearing line. b Press and hold the Select button on the Operating Panel (or the left mouse button) c Move the cursor to change the direction of the bearing line.
Getting started Modifying the amount of visual aids (cosmetics) on the presentation Purpose The choices in the Cosmetics menu allows you to enable or disable a range of visual aids in the sonar picture. Procedure 1 Click the Display tab to open the menu. 2 Click the Cosmetics button to open the Cosmetics menu. This menu allows you to control the amount of support information on the SH90 presentation.
Simrad SH90 Cosmetics: Bearing Card, Wind Marker and Distance Rings Bearing Card The Bearing Card (A) shows the current bearing relative to the vessel. The markers are shown as short white lines for every 10th degree along the outer circle of the sonar view. Wind Marker B 400 300 200 100 C The Wind Marker (B) is shown as an arrow drawn from the Compass card pointing towards the centre of the display. If a wind sensor is connected to the sonar, it will A automatically show the current wind direction.
Getting started Cosmetics: Variable Range Marker, Compass Card and Vertical Ring Variable Range Marker (VRM) The Variable Range Marker (VRM) (D) consists of an adjustable range ring with range read-out. It can be used for any type of distance marking relative to the vessel. To adjust the marker, locate the cursor on the marker ring, press the Select on the Operating Panel, and move the cursor with the Select button depressed.
Simrad SH90 Cosmetics: Depth Dividers, Minute Markers and Bow Marker Depth Dividers The Depth Dividers (G) are horizontal dotted lines used to visualize the depth steps in the vertical slices. Minute Marker The Minute Markers (H) are shown as small circles on the track history of the ship. Bow Marker The Bow Marker (I) is heading marker. It is a dotted line drawn from the bow of your own ship.
Getting started 2 Click the middle of the Range button to open the parameter dialog. 3 In the parameter dialog, click the Help button. Once pressed, the first help text will appear in the bottom of the menu. This is the On-line text. It is short, context sensitive, and designed not to interrupt the operation of the sonar. 4 In the help dialog, click the Free button. This will open the complete interactive manual.
Simrad SH90 Operational procedures This chapter contains several operational procedures explaining how you can put your Simrad SH90 to use. Are there any procedures missing? Are you performing an operation that we have not explained? Write an e-mail to simrad.support@simrad.com and let us know. We may then include the procedure in the next version of this manual.
Operational procedures Menu procedures This section provides general procedures for menu handling. Topics • Hiding (and retrieving) the menu on page 59 • Simplifying the menu system with fewer buttons on page 59 Hiding (and retrieving) the menu The menu is normally located on the right hand side of the display presentation, but if you don't need it, you can easily remove it. 1 Basic procedure a Press the Menu button on the Operating Panel. The Menu button acts as a toggle switch.
Simrad SH90 Gain and filter adjustment procedures This section explains how to control the manual and automatic gain settings on the SH90 sonar.
Operational procedures 2 Alternative method: Horizontal gain a Click the Horizontal tab to open the menu. b On the Horizontal menu, click Gain. This parameter is used to control the receiver gain, that is how much amplification that is used on the received echoes. c 3 Click either side of the button to leaf through the options, or the middle of the button to open the parameter dialog. Alternative method: Vertical gain a Click the Vertical tab to open the menu. b On the Vertical menu, click Gain.
Simrad SH90 Tip The most practical way to use the AGC (Automatic Gain Control) is to first switch it off. Adjust the echo presentation using the gain until you have the best possible result, then activate the AGC. The AGC works best with even background (homogenous noise conditions) and pronounced targets. With uniform sonar conditions you may benefit from strong AGC compensation. However, if you are looking at scattered fish, reduce the AGC, and try to add gain instead.
Operational procedures Note When this parameter is changed on a horizontal menu, the chosen setting is only put to use on the horizontal sonar presentation. If you change the parameter on a vertical menu, it is only applied to the vertical sonar slice presentation. Tip We recommend that the RCG is active all the time, but be careful in the vertical presentation. The Reverberation Controlled Gain (RCG) works best on small schools. Setting “1” is intended for schools.
Simrad SH90 Tip For scattered fish, we suggest that you use the 40 log R setting. For small schools, try 30 log R, for large schools, use 20 log R. If you use 20 log R the bottom will always be presented with the same echo strength. If you wish to examine weak echoes very close to your vessel, you may wish to use 10 log R or 5 log R, or turn off the TVG. Keep in mind that the filters in the SH90 are implemented in “series”. The TVG compensations are made before the AGC (Automatic Gain Control).
Operational procedures Mode procedures This section explains how to choose presentation modes, and how to set up the Mode buttons on the SH90 Operating Panel. Topics • Select presentation mode on page 65 • Defining the function of the Mode buttons on the Operating Panel on page 65 • Sorting the presentation modes on page 66 Related topics • Presentation modes on page 82 Select presentation mode Your SH90 sonar is equipped with several presentation modes.

When you click the button, this will activate the on-screen keyboard used to type the required 32-character code word.
Simrad SH90 Presentation modes The SH90 sonar provides you with several different presentation modes. These have been created to cover all your operational needs for various types of fishing and fishing gear. Bow up When Bow up mode is selected, the vessel symbol is stationary on the screen with the bow pointing upwards. The echo presentation covers 360 degrees around the vessel, and all echoes are updated for every ping.
Presentation modes Bow up/Dual Vertical When Bow up/Dual vertical mode is selected, the upper part of the screen shows a curtailed bow-up presentation, while the lower part shows two vertical slice presentations. The bearing of the left vertical presentation is indicated by the white audio line in the horizontal presentation, while the bearing of the right vertical presentation is indicated by the yellow-dashed line.
Simrad SH90 North up When North up mode is selected, true north is always up on the screen. The vessel symbol is stationary with the bow pointing in the vessel’s course direction. The movement of the echoes across the screen are controlled by a combination of the vessel’s course and speed and the target’s own movements. Dual 1 The Dual 1 mode is a kind of “two sonars in one” operation, where each presentation is updated for every second transmission.
Operating Panel Operating Panel The frequently used functions are directly accessible by the designated control buttons on the Operating Panel, and may enter operational commands directly. The buttons are grouped in fields according to their purpose. Most sonar functions are also accessible and activated using the menu system on the display and the trackball and Select button on the Operating Panel.

Simrad SH90 Range This is where you select the range in the horizontal and vertical presentations. Cursor The trackball is used to move the cursor on the display. The Menu button is used to hide the menu, while the Select button is used to make selections on the display. The View and Object buttons open specific short-cut menus. → Controlling the cursor on page 25 Tilt These are the buttons used to tilt the sonar beam up or down. You can also start an automatic tilt program to carry out automatic searches.
Menu system Menu system The Simrad SH90 sonar is equipped with an extensive menu system, and you will use this to choose parameters for the various operational modes and functions. The chapter gives you a short description of each menu choice. This chapter does not describe all the menu buttons on the SH90. For a complete description of these, refer to the SH90 Reference Manual. In order to select active menu and to click the various buttons, you must use the cursor.
Simrad SH90 Horizontal menu The Horizontal menu is used to control the horizontal presentations. The parameters chosen are present in all presentation modes. When a horizontal parameter setting is selected and defined in one mode, the chosen settings will automatically be applied to all modes. The Horizontal 2 menu is identical to the Horizontal menu. It is used during Dual 1 and Dual 2 operations. Parameters 1 Mode The purpose of the Mode button is to choose the presentation mode.
Menu system 8 Beam This parameter allows you to control the vertical beam width in the horizontal presentation. 9 Frequency This parameter is used to control the transmitter and receiver operational frequency. 10 TVG This parameter allows you to choose the Time Variable Gain setting in the SH90. This function will automatically adjust the gain in the SH90 to compensate for geometric spreading and absorption. 11 AGC This parameter controls the Automatic Gain Control.
Simrad SH90 Vertical menu The Vertical menu is only shown in modes with a vertical slice function. All relevant settings, except the TX Power, can be selected separately for the vertical modes independent of the horizontal settings. When any vertical setting is selected and defined in one mode, the setting will be applied to all vertical modes. Parameters 1 Mode The purpose of the Mode button is to choose the presentation mode.
Menu system 8 TVG This parameter allows you to choose the Time Variable Gain setting in the SH90. This function will automatically adjust the gain in the SH90 to compensate for geometric spreading and absorption. 9 AGC This parameter controls the Automatic Gain Control. This function will automatically reduce the gain if you experience reverberation and noise, or increase it if the conditions permit it. 10 RCG This parameter is used to control the Reverberation Controlled Gain.
Simrad SH90 Vertical 180 menu The Vertical 180 menu is only shown when the Bow up/180° Vertical mode is chosen. All relevant settings, except the TX Power, can be selected separately for the vertical modes independent of the horizontal settings. When any vertical setting is selected and defined in one mode, the setting will be applied to all vertical modes. The Tip button is only available on this menu. The Tip button is used to tip the vertical slice to avoid the blind zone.
Menu system 8 Frequency This parameter is used to control the transmitter and receiver operational frequency. 9 TVG This parameter allows you to choose the Time Variable Gain setting in the SH90. This function will automatically adjust the gain in the SH90 to compensate for geometric spreading and absorption. 10 AGC This parameter controls the Automatic Gain Control. This function will automatically reduce the gain if you experience reverberation and noise, or increase it if the conditions permit it.
Simrad SH90 Display menu The Display menu is shown in all presentation modes, and provides access to parameters controlling the visual presentation of the SH90 presentations. Note that some of the choices on the menu are simple on/off buttons. Parameters 1 Mode The purpose of the Mode button is to choose the presentation mode. 2 Full Screen This is an on/off switch. When switched “on” the menu system is removed from the SH90 presentation.
Menu system 9 Mode buttons Use this button to choose how the Mode buttons on the Operating Panel shall work. You can either choose between the four most frequent modes, or the four most frequent user settings. Mode 1 10 Language Use this function to choose the language used on the menu buttons. 11 Units This parameter allows you to choose the measurement units used by the SH90.
Simrad SH90 Setup menu The Setup menu is shown in all presentation modes, and gives access to parameters controlling the processing and algorithms in the SH90. It also provides access to specific system parameters and functions such as Test and Store/Recall. Parameters 1 Mode The purpose of the Mode button is to choose the presentation mode. 2 Store/Recall Click this button to record and playback SH90 images. 3 Test Click this button to access the test software in the SH90.
Menu system This command enables you to adjust the size of the “window” the SH90 places on the chosen target. The SH90 will use the echoes detected within this “window” to control the tracking. 10 Wind direction If you do not have a wind sensor connected to your SH90, you can use this parameter to set the wind direction manually. 11 Wind speed This is not a parameter. It is only a presentation of the current wind speed provided that a wind sensor is connected to the SH90.
Simrad SH90 Objects menu The Objects menu is shown in all presentation modes, and displays the Range (R), Bearing (B) and Depth (D) to all selected objects.
Menu system 3 DeleteAll (objects) Click once to delete all current objects from the Objects menu. 4 Inspect Object The Inspect Object parameter dialog allows you to investigate the specific parameters for each selected object. The parameter dialog opens automatically when you click on one of the object IDs. 5 Status The Status parameter dialog contains a transducer position indicator, as well as presentation of current time, date, latitude, longitude, heading and speed.
Simrad SH90 This menu provides several sensor measurements and test functions for operational and functional tests. Note that tests are designed only to be carried out by qualified service engineers. From this menu you can also access the Message Bar configuration. → Setup menu on page 96 Sort Modes menu This menu is used to select the presentation modes to be activated by the four Mode buttons on the Operating Panel.
Sonar theory Sonar theory This chapter explains some of the basic theory related to settings, error sources and noise conditions. Topics • Parameters on page 101 • Noise and reverberation on page 106 • Layers and deflections on page 109 Parameters A sonar will transmit a sound wave into the water around the vessel. When this sound wave hits fish, bottom, or other objects in the water, a part of the sound will be returned as echoes.
Simrad SH90 What is TVG? TVG means Time Varied Gain. As echoes will be weaker when the distance to them increase, the sonar will automatically amplify distant echoes more than close echoes. In practice, the gain will increase in proportion with how long the sonar must wait for the echoes. Figure 4 The TVG principle: The gain at time (B) is larger than at time (A) (CD015005-003) C A 0 1 10 B 100 1000 When you choose the TVG setting you can either switch it off, or choose a “X log R” value.
Sonar theory the sonar’s maximum range. As show in the menu, the AGC has four different settings. These settings define the difference between the maximum and minimum echo level for the filter to take effect. Tip The most practical way to use the AGC (Automatic Gain Control) is to first switch it off. Adjust the echo presentation using the gain until you have the best possible result, then activate the AGC. The AGC works best with even background (homogenous noise conditions) and pronounced targets.
Simrad SH90 CW means continuous wave, which means that the transmission frequency is fixed during the entire pulse. When you use CW transmission you can choose the length of the pulses. In a search phase under good conditions, you should try setting Long. If the conditions worsen, try to shorten the pulse length. This will make it easier to distinguish the various echoes, and the reverberation will be reduced. The default setting on the SH90 sonar is FM Auto.
Sonar theory If you have too much gain, you will see a sonar picture with too many echoes. This is because the large amplification presents all kind of noise and reverberation that the sonar picks up. If the gain is smaller the noise and reverberation will disappear, but if it the gain is too small the fish echoes may disappear as well. In most cases you should try with a medium value. On this sonar, you can adjust the horizontal and vertical gain independent of each other.
Simrad SH90 Figure 6 Tilt C A B (CD015005D) The challenge will always be to find a tilt that prevents the fish echoes to be buried in reverberation and bottom echoes. If you use a high tilt value (A) the fish will easily be disguised by the bottom echoes, but a strong RCG setting will help. As the distance from the bottom to the fish increases, the fish will be easier to see when the RCG removes the bottom echoes.
Sonar theory • Reverberation on page 107 • Blocking on page 108 • Check the noise yourself! on page 108 Cavitation As the propeller blades move through the water, low pressure areas are formed as the water accelerates around and moves past the blades. The faster the blades move, the lower the pressure around it will become. As it reaches vapour pressure, the water vaporizes and forms small bubbles of gas. This is cavitation.
Simrad SH90 Figure 8 Reverberation B A (CD015005E) The echoes from the bottom will vary with how uneven the bottom is, what kind of bottom you have under your vessel, (rock, mud, sand etc.) as well as your current tilt setting. The echo from the sea surface will vary with the current sea state and your current tilt setting. The illustration demonstrates how the bottom and the sea surface return echoes back to your sonar transducer.
Sonar theory The level your read in the button is the current noise in the direction of the cursor. The noise is provided in dB, and the number should be as small as possible. In order to reduce the noise, try to adjust the propeller pitch and the number of revolutions. How to check for electrical noise This procedure provides a simple method to check the electrical noise. 1 Switch off all electric equipment that can cause electrical noise.
Simrad SH90 Deflections On warm days – especially during summer – the sea surface will be heated by the sun, and the water temperature will gradually decrease with increasing depth. Figure 10 Water temperatures on warm days B A (CD015005G) When the temperature decreases (A) closer to the bottom, the sonar beam is deflected down as indicated by the illustration. The school of fish (B) you thought you would see is not visible at all.
