SAFETY INSTRUCTIONS WARNING Radio Frequency Radiation Hazard The radar antenna emits electromagnetic radio frequency (RF) energy which can be harmful, particularly to your eyes. Never look directly into the antenna aperture from a close distance while the radar is in operation or expose yourself to the transmitting antenna at a close distance. Distances at which RF radiation levels of 100 and 10 W/m2 exist are given in the table below.
PAGE 5
SAFETY INSTRUCTIONS WARNING ELECTRICAL SHOCK HAZARD WARNING Use the proper fuse. Do not open the equipment. Only qualified personnel should work inside the equipment. Turn off the radar power switch before servicing the antenna unit. Post a warning sign near the switch indicating it should not be turned on while the antenna unit is being serviced. Prevent the potential risk of being struck by the rotating antenna and exposure to RF radiation hazard.
PAGE 6
SAFETY INSTRUCTIONS CAUTION WARNING No one navigational aid should be relied upon for the safety of vessel and crew. The navigator has the responsibility to check all aids available to confirm position. Electronic aids are not a substitute for basic navigational principles and common sense. • This ARP automatically tracks automatically or manually acquired radar targets and calculates their courses and speeds, indicating them by vectors.

PAGE 43
1. RADAR OPERATION 1.12 Presentation Modes This radar has the following presentation modes: Relative Motion (RM) Head-up: Unstabilized Head-up TB: Head-up with compass-stabilized bearing scale (True Bearing) where the bearing scale rotates with the compass reading. Course-up: Compass-stabilized relative to ship’s orientation at the time of selecting course-up. North-up: Compass-stabilized with reference to north Stern-up: The radar image is rotated 180°.
PAGE 44
1. RADAR OPERATION 1.12.2 Description of presentation modes Head-up mode The head-up mode is a display in which the line connecting own ship and the top of the display indicates own ship’s heading. The target pips are painted at their measured distances and in their directions relative to own ship’s heading. A short line on the bearing scale is the north marker indicating heading sensor north. A failure of the heading sensor input will cause the north marker to disappear and the readout to show ***.
PAGE 45
1. RADAR OPERATION Head-up TB (True Bearing) mode Radar echoes are shown in the same way as in the head-up mode. The difference from normal head-up presentation lies in the orientation of the bearing scale. The bearing scale is heading sensor stabilized. That is, it rotates in accordance with the heading sensor signal, enabling you to know own ship’s heading at a glance. This mode is available when the radar is interfaced with a gyro heading sensor.
PAGE 46
1. RADAR OPERATION True motion mode Own ship and other moving objects move in accordance with their true courses and speed. In ground stabilized TM, all fixed targets, such as landmasses, appear as stationary echoes. In the sea stabilized TM without set and drift inputs, the landmass can move on the screen. Note that true motion is not available on the 72 nm (non-IMO type only) or 96 nm range scale.
PAGE 47
1. RADAR OPERATION 1.13 Entering Own Ship's Speed The ARP and azimuth stabilized presentation modes require own ship speed input and compass signal. The speed can be entered from a log (STW) or GPS (SOG) or manually on the menu. Note that FURUNO GPS Navigator GP-90 provides COG and SOG. 1.13.1 Automatic speed input by log or GPS navigator 1. Roll the trackball to place the arrow in the SPD box at the top right corner of the screen. 2. Push the right button to display the SPEED menu.
PAGE 48
1. RADAR OPERATION 1.13.2 Manual speed input If the speed log is not working, enter speed manually as below. In this case the speed data type is shown as MANUAL and is speed thru water (STW). Note that, for the IMO specification radar, manual speed input is not available when the AIS feature is active. 1. Roll the trackball to place the arrow in the SPD box at the top right corner of the screen. 2. Push the right button to display the SPEED menu. 3.
PAGE 49
1. RADAR OPERATION 1.15 Choosing the Pulselength The pulselength in use is displayed at the upper-left position of the screen using the indications shown in the table below. Label and pulselength Indication Pulselength (μs) S1 (Short pulse 1) 0.07 S2 (Short pulse 2) 0.15 M1 (Medium pulse 1) 0.3 M2 (Medium pulse 2) 0.5 M3 (Medium pulse 3) 0.7 L (Long pulse) 1.2 *: S, M1, M2 and L on FAR-2157(-BB) and S-band radars.

PAGE 51
1. RADAR OPERATION 1.16 Adjusting the Sensitivity The gain control adjusts the sensitivity of the receiver. The proper setting is such that the background noise is just visible on the screen. If you set up for too little sensitivity, weak echoes may be missed. On the other hand excessive sensitivity yields too much background noise; strong targets may be missed because of the poor contrast between desired echoes and the background noise on the display.
PAGE 52
1. RADAR OPERATION 1.17 Suppressing Sea Clutter Echoes from waves cover the central part of the display with random signals known as sea clutter. The higher the waves, and the higher the antenna above the water, the further the clutter will extend. When sea clutter masks the picture, suppress it by the A/C SEA control, either manually or automatically. 1.17.1 Choosing method of adjustment 1. Roll the trackball to choose SEA AUTO or SEA MAN (whichever is shown) at the top of the display.
PAGE 53
1. RADAR OPERATION By trackball 1. Choose SEA AUTO following the procedure in paragraph 1.17.1. 2. Roll the trackball to place the arrow in the A/C SEA level indicator at the top of the display. 3. While observing the A/C SEA level indicator, roll the wheel downward to increase the A/C SEA or upward to decrease it. 100 levels (0-100) are available. 1.17.
PAGE 54
1. RADAR OPERATION 1.18 Suppressing Rain Clutter Use the AUTO RAIN and A/C RAIN to suppress rain clutter. AUTO RAIN suppresses rain clutter in the picture and A/C RAIN suppresses clutter picked up by the antenna. 1.18.1 Turning AUTO RAIN on or off 1. Roll the trackball to choose the PICTURE box at the left side of the screen. 2. Push the right button to show the PICTURE menu.
PAGE 55
1. RADAR OPERATION 1.18.2 Adjusting A/C RAIN The vertical beam width of the antenna is designed to see surface targets even when the ship is rolling. However, by this design the unit will also detect rain clutter (rain, snow, or hail) in the same manner as normal targets. The A/C RAIN control adjusts the receiver sensitivity as the A/C SEA control does but rather in a longer time period (longer range). The higher the setting the greater the anti-clutter effect.
PAGE 56
1. RADAR OPERATION 1.19 Interference Rejector Mutual radar interference may occur in the vicinity of another shipborne radar operating in the same frequency band. It is seen on the screen as a number of bright spikes either in irregular patterns or in the form of usually curved spoke-like dotted lines extending from the center to the edge of the picture. Activating the interference rejector circuit can reduce this type of interference. The interference rejector is a kind of signal correlation circuit.
PAGE 57
1. RADAR OPERATION 1.20 Measuring the Range The range to a target may be measured three ways: with the fixed range rings, with the cursor, or with the VRM. Use the fixed range rings to obtain a rough estimate of the range to a target. They are the concentric solid circles about own ship, or the sweep origin. The number of rings is automatically determined by the selected range scale and their interval is displayed at the upper-left position of the screen.
PAGE 58
1. RADAR OPERATION 1.20.2 Measuring range by the variable range marker (VRM) There are two VRMs, No. 1 and No. 2, which appear as dashed rings so that you can discriminate them from the fixed range rings. The two VRMs can be distinguished from each other by different lengths of dashes. 340 No. 1 VRM 350 000 010 020 330 030 320 Target blip 040 310 050 060 300 070 290 280 080 270 090 260 100 250 110 240 120 230 No. 2 VRM 130 140 220 210 150 200 190 180 170 160 >0.66NM< VRM2 1.
PAGE 59
1. RADAR OPERATION 5. Push the left button to anchor the VRM and fix its readout, or push the right button to return the VRM to its previous location (range). 6. To erase a VRM, choose the appropriate VRM readout box and then push the left button until the VRM disappears from the screen. 1.20.3 Choosing VRM unit of measurement (B, C and W types) 1. Roll the trackball to choose the MENU box at the right side of the screen. The guidance box at the bottom right corner now reads “DISP MAIN MENU.” 2.
PAGE 60
1. RADAR OPERATION By trackball 1. Roll the trackball to place the arrow in the EBL1 or EBL2 box, whichever EBL you want to use. EBL1 EBL2 EBL boxes 2. The guidance box reads “EBL ON/.” Push the left button to turn on the EBL. The guidance box now reads “EBL SET L=DELETE /.” 3. Push the left button again and the cursor jumps to inside the effective display area. The guidance box now reads “EBL FIX L=DELETE/.” 4.
PAGE 61
1. RADAR OPERATION 1.21.2 Choosing true or relative bearing The EBL readout is affixed by “R.” (relative) if it is relative to own ship's heading, ”T.” (true) if it is referenced to the north. You may choose relative or true in the head-up modes; in all other modes it is always TRUE. To choose bearing reference in the head-up mode, do the following: 1. Roll the trackball to choose the MENU box and then push the left button to open the MAIN menu. 2.
PAGE 62
1. RADAR OPERATION 1.22 Collision Assessment by Offset EBL The origin of the EBL can be placed anywhere with the trackball to enable measurement of range and bearing between any targets. This function is also useful for assessment of the potential risk of collision. It is possible to read CPA (Closest Point of Approach) by using a VRM as shown below (Figure (a)). If the EBL passes through the sweep origin (own ship) as illustrated (Figure (b)), the target ship is on a collision course. 1.22.

1. RADAR OPERATION 1.24 Setting a Target Alarm The target alarm serves to alert the navigator to targets (ships, landmasses, etc.) entering a set area, with audible and visual alarms. CAUTION The guard alarm zone has a fixed width of 0.5 nm in the radial direction (depth) and is adjustable from 3.0 to 6.0 nm (guard zone 1) and any distance (guard zone 2). On the Non-IMO radar the boundaries can be set at any distance.
PAGE 66
1. RADAR OPERATION Note 1: If you wish to create a target alarm zone having a 360-degree coverage around own ship, set point “B” in almost the same direction as point “A.” Note 2: Two target alarm zones may be set. Note however that the 2nd target alarm zone is available only when the 1st target alarm zone is active. Note 3: When the target alarm zone is not within the range in use the indication UP RNG appears to the right of the ALARM box.

1. RADAR OPERATION 1.25 Off-Centering the Display Own ship position, or sweep origin, can be displaced to expand the view field without switching to a larger range scale. The sweep origin can be off-centered to the cursor position, but not more than 75% of the range in use; if the cursor is set beyond 75% of the range scale, the sweep origin will be off-centered to the point of 75% of the limit.
PAGE 69
1. RADAR OPERATION 1.26 Echo Stretch The echo stretch feature enlarges targets in the range and bearing directions to make them easier to see, and it is available on any range. There are three types of echo stretch, 1, 2 and 3, and the higher the number the greater the amount of stretching. Note: The echo stretch magnifies not only small target pips but also returns (clutter) from sea surface, rain and radar interference.
PAGE 70
1. RADAR OPERATION 1.27 Echo Averaging The echo averaging feature effectively suppresses sea clutter. Echoes received from stable targets such as ships appear on the screen at almost the same position every rotation of the antenna. On the other hand, unstable echoes such as sea clutter appear at random positions. To distinguish real target echoes from sea clutter, echoes are averaged over successive picture frames.
PAGE 71
1. RADAR OPERATION 1.28 Target Trails The trails of the radar echoes of targets may be displayed in the form of synthetic afterglow. Target trails are chosen either relative or true and may be sea or ground stabilized. True motion trails require a compass signal and own ship speed input. 1.28.1 True or relative trails You may display echo trails in true or relative motion (only true trail on TM). Relative trails show relative movements between targets and own ship.

1. RADAR OPERATION 1.28.4 Saving, copying target trails By turning on the functions TRAIL RESTART and TRAIL COPY, you may continue painting target trails whenever the range scale is changed. The amount of range change determines how the radar paints trails. See the table below for details. Note however that if the previous range is restored within 10 seconds and the amount of range change is within 1/3, trails continue as before. If trails become difficult to view trails, you may delete them.
PAGE 74
1. RADAR OPERATION The relationship between trail restart and trail copy depends on their status, as shown in the table below. 1.28.5 Trail restart Trail copy Trail status ON ON Range changed while trail is ON: Trails continue on targets within previous range. ON OFF Range changed while trail is ON: Trails within the previous range are erased and then trails are restarted. OFF OFF/ON • Range changed while trail is ON: New trails not initiated. (Trails from previous range are stored in memory.

2. RADAR OBSERVATION 2.1 General 2.1.1 Minimum and maximum ranges Minimum range The minimum range is defined by the shortest distance at which, using a scale of 1.5 or 0.75 nm, a target having an echoing area of 10 m2 is still shown separate from the point representing the antenna position. It is mainly dependent on the pulselength, antenna height, and signal processing such as main bang suppression and digital quantization.
PAGE 120
2. RADAR OBSERVATION X-band and S-band In fair weather, the equation on the previous page does not give a significant difference between X- and S-band radars. However, in heavy precipitation condition, an S-band radar would have better detection than an X-band radar. Radar resolution There are two important factors in radar resolution (discrimination): bearing resolution and range resolution.
PAGE 121
2. RADAR OBSERVATION 2.2 False Echoes Occasionally echo signals appear on the screen at positions where there is no target or disappear even if there are targets. They are, however, recognized if you understand the reason why they are displayed. Typical false echoes are shown below. Multiple echoes Multiple echoes occur when a transmitted pulse returns from a solid object like a large ship, bridge, or breakwater.
PAGE 122
2. RADAR OBSERVATION Virtual image A relatively large target close to your ship may be represented at two positions on the screen. One of them is the true echo directly reflected by the target and the other is a false echo which is caused by the mirror effect of a large object on or close to your ship as shown in the figure below. If your ship comes close to a large metal bridge, for example, such a false echo may temporarily be seen on the screen.

2. RADAR OBSERVATION 2.3 SART (Search and Rescue Transponder) 2.3.1 SART description A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm) radar within a range of approximately 8 nm. Each radar pulse received causes it to transmit a response which is swept repetitively across the complete radar frequency band. When interrogated, it first sweeps rapidly (0.4 µs) through the band before beginning a relatively slow sweep (7.5 µs) through the band back to the starting frequency.
PAGE 124
2. RADAR OBSERVATION 2.3.2 Showing SART marks on the radar display This radar is equipped with a feature which optimally sets up the radar for SART detection. This feature automatically detunes the radar receiver out of its best tuning condition. This erases or weakens all normal radar echoes, but the SART marks are not erased because the SART response signal scans over all frequencies in the 9 GHz band.
PAGE 125
2. RADAR OBSERVATION 2.3.3 General remarks on receiving SART SART range errors When responses from only the 12 low frequency sweeps are visible (when the SART is at a range greater than about 1 nm), the position at which the first dot is displayed may be as much as 0.64 nm beyond the true position of the SART. When the range closes so that the fast sweep responses are seen also, the first of these will be no more than 150 meters beyond the true position.
PAGE 126
2. RADAR OBSERVATION 2.4 RACON A RACON is a radar beacon which emits radar receivable signals in the radar frequency spectrum (X- or S-band). There are several signal formats; in general, the RACON signal appears on the radar screen as a rectangular echo originating at a point just beyond the position of the radar beacon. It has a Morse coded pattern. Note that the position on the radar display is not accurate.

PAGE 161
3. ARP OPERATION 3.17 Criteria for Selecting Targets for Tracking The FURUNO ARP video processor detects targets in midst of noise and discriminates radar echoes on the basis of their size. Target whose echo measurements are greater than those of the largest ship in range or tangential extent are usually land and are displayed only as normal radar video.
PAGE 162
3. ARP OPERATION This land outline is used to inhibit further acquisition and tracking of ship-sized echoes beyond the closest coast outline. Five consecutive scans of coastal outline are retained in memory to allow for signal variation. All smaller echoes are declared to be ship sized and the middle of the leading edge is used to provide precise range and bearing coordinates of each echo on every scan. This range/bearing data is matched to previous data and analyzed from scan-to-scan for consistency.
PAGE 163
3. ARP OPERATION 3.18 Factors Affecting ARP Functions Sea returns If the radar anti-clutter control is adjusted properly, there is no serious effect because distant wave clutter, not eliminated by this control, is filtered out by more than one bang correlation and scan-to-scan matching of data. Rain and snow Clutter can be acquired and tracked as targets. Adjust the A/C RAIN control. If it is heavy rain, switch to S-band if provided, or switch on the interference rejector on the radar.
PAGE 164
3. ARP OPERATION Blind and shadow sectors Radar shadow or blind areas caused by obstructions aboard ship, for example, funnels and masts, in the path of the radar beam can result in reduction of radar beam intensity in that particular direction. This may eliminate the detection of some targets. The ARP system will lose track of targets shortly after they are lost on the radar picture and if they remain in a blind zone.
PAGE 165
4. AIS OPERATION The FURUNO AIS (Automatic Identification System) model FA-100 or FA-150 exchanges with other AIS-fitted ships all data and information required by the SOLAS 1994 as amended. However, they are displayed in text form. By interfacing the FA-100 or FA-150 with this radar, the AIS information is graphically indicated together with the radar and ARP information. This radar accepts position data fixed by WGS-84 geodetic datum. Set the datum to WGS-84 on the EPFS (GPS, etc.

4. AIS OPERATION 4.12 Fusion of ARP and AIS Targets An AIS-equipped ship is usually displayed by two symbols on the radar display. This is because the AIS ship position is measured by a GPS navigator (L/L) on that ship whereas the radar detects the same ship by PPI principle (range and bearing relative to own ship radar antenna). To avoid the presentation of two target symbols for the same physical target, the “fusion” function is incorporated.

APPENDIX 4. Longitude Error Table (on 96 nm range scale) The longitude lines concentrate on the north pole and south pole, namely, 1 nm is equivalent to 1 minute at 0 degree latitude, 2 minutes at 60 degrees latitude, 3 minutes at 70 degrees latitude and so on. For this reason, a longitude error occurs on the radar display. For example, when own ship is at 60°N and 135°E, even if the cursor indication is 62°N and 139°E, the real cursor position is deviated to the left (west) side.
