Simrad SH90 SIMRAD SH90 Study this chapter to familiarize yourself with the Simrad SH90 Fish finding sonar system. Topics • Basic information on page 5 • Main units on page 5 • System diagram on page 8 • Basic functionality on page 9 Basic information The Simrad SH90 is an omnidirectional high frequency sonar. It is designed for all sized fishing vessels, both purse seiners and trawlers. The operational frequency is 114 kHz.
Simrad SH90 Wheelhouse units Colour Monitor The Colour display is a high-resolution monitor. In addition to the sonar picture, the monitor will also display the user menus for the interactive operation. In order to ease the situation comprehension, certain colours have been chosen to better the distinction between the various elements in the scene. The colour display is not a part of the sonar delivery, and it must be purchased locally.
Simrad SH90 This computer serves several functions. It performs the advanced signal processing required to present the information on the display, and it allows you to control the sonar. It provides the graphic presentation of the sonar modes and the images created, it holds the menu system, it communicates with the Transceiver Unit, and reads information from peripheral units. Operating Panel power supply A small power supply is implemented to provide stand-by power to the Operating Panel.
Simrad SH90 Transducer The cylindrical Transducer allows the sonar beam to give full 360 degrees coverage of the water volume down to -60 degrees.
Simrad SH90 Basic functionality 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 Figure 5 60 degrees vertical slice This vertical slice, which is presented by the white audio line in the horizontal picture, can be selected to any bearing by the manual training control. The combination of the Omni mode and the vertical slice will give an optimal visualization of the catch situation. Figure 6 Omni/vertical combination In addition to the Omni picture, the vertical slice is especially useful for visualizing the vertical distribution of a school of fish.
Simrad SH90 When the beam stabilizer is activated, both horizontal and vertical beams will be stabilized electronically for roll and pitch movements up to ±20 degrees. The beam direction will then change continuously according to the vessel’s movements, and secure an optimal contact with the targets even in rough seas. Figure 7 Stabilisation system Reception A great effort has been made to reduce unwanted noise to get a clean and stable echo presentation.
Simrad SH90 RCG (Reverberation Controlled Gain) The RCG function adjust the picture to minimize influence from bottom and surface reverberation. The strength of the filter can be selected in the menu. With maximum strength is selected, the RCG will effectively reduce the bottom in shallow water, while variations on the bottom will be displayed. Note that scattered fish can be perceived as reverberation. The RCG filter must therefore be used with care if scattered schools are to be detected.
Simrad SH90 When the stabilising system is active, the tilt angle for each beam will automatically be corrected relative to the vessel’s pitch and roll movements.
Simrad SH90 MENU SYSTEM The Simrad SH90 Fish finding sonar comprises a large number of different menus on several levels. Menus are selected by pressing their respective tabs on the right hand side, and the appearance of menus and tabs depends on the chosen operational mode and the current settings. Each menu button displays the current parameter setting. The menu system is available in several languages. Figure 8 Menu elements A Sonar type: This field simply states the name of the sonar.
Operating panel OPERATING PANEL The most 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 EXAMPLES This page presents several screen captures taken from actual operations on fishing vessels. Figure 10 1200 meters This screen capture shows schools on port side at 1200 meters range. Also, a small school of fish is located approximately 1100 meter aft of the vessel. Figure 11 Tuna A 10 tons school of tuna has been detected, and tracking has been started. The tracking functionality is vital for the success of the catch.
Examples Figure 12 Herring In this screen capture a school of herring has detected, and it now evaluated by the skipper. Target tracking is activated, and in the lower left corner the school’s heading, distance from the vessel, and speed is displayed. The 180° vertical view is activated, and can be seen in the lower part of the screen. The school is just lifting from the bottom, and it has a good density. Figure 13 Sand eel This sonar presentation is taken from a trawler fishing for sand eel.
