SAFETY INSTRUCTIONS  ii Mandatory Action Prohibitive ActionWARNINGIndicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.CAUTIONIndicates a potentially hazardous situation which, if not avoided, can result in minor or moderate injury.  Warning, CautionSAFETY INSTRUCTIONSThe operator and installer must read the applicable safety instructions before attempting toinstall or operate the equipment. WARNING             Radio Frequency Radiation HazardThe 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 distancewhile the radar ius in operation or eexpose yourself to the transmitting antenna at a close distance. Distances at which RF radiation level of 100, 50 and 10 W/m  are given in the table below.   Note: If the antenna unit is installed at a close distance in front of the wheel house, youradministration may require halt of transmission within a certain sector of antenna revolution.This is possible. Ask your FURUNO representive or dealer to provide this feature. 2DANGERIndicates a potentially hazardous situation which, if not avoided, will result in death or serious injury.*1 XN12AF: 120cm, XN20AF: 198cm, XN24AF: 243cm, SN30AF: 309cm, SN36AF: 377cm100W/m  2Radar modelFAR-2127/2827FAR-2117/2817XN12AFXN20AFXN24AFXN12AFXN20AFXN24AFSN30AF0.3m0.1m0.1m0.9m0.5m0.2mFAR-2137S/2837SXN20AFFAR-2837SWFAR-2827WTransceiver MagnetronRTR-079A MG5436RTR-078ARTR-080RTR-081ARTR-082      MAF-1565NMG5223FMG5436MG5223F SN36AFAntenna *10.1m0.4m10W/m  23.7m2.2m1.5m9.0m4.6m3.3m2.4m5.6m1.9m50W/m  21.2m0.7m0.4m2.6m1.7m1.0m1.0m0.2mSN36AF 0.1m 2.0m0.7mXN24AF 0.2m 3.4m0.5m-
SAFETY INSTRUCTIONS  iiiWARNINGELECTRICAL SHOCK HAZARDDo not open the equipment.Only qualified personnelshould work inside theequipment.Turn off the radar powerswitch before servicing the antenna unit. Post a warn-ing sign near the switchindicating it should not beturned on while the antennaunit is being serviced.Prevent the potential risk ofbeing struck by the rotatingantenna and exposure to RF radiation hazard.Wear a safety belt and hardhat when working on the antenna unit.Serious injury or death canresult if someone falls fromthe radar antenna mast.Do not disassemble or modify theequipment.Fire, electrical shock or serious injury canresult.Immediately turn off the power at theship's mains switchboard if waterleaks into the equipment or the equip-ment is emitting smoke or fire.Continued use can cause fatal damage tothe equipment.WARNINGUse the proper fuse.Use of a wrong fuse can result in damageto the equipment or cause fire.Keep heater away from equipment.Heat can alter equipment shape and meltthe power cord, which can cause fire orelectrical shock.Do not place liquid-filled containersnear the equipment.Fire or electrical shock can result if a liquidspills into the equipment.Do not operate the equipment with wethands.Electrical shock can result.Before servicing the radar, turn offthe appropriate external breaker.Power is not removed from the radar simply by turning off its power switch.
SAFETY INSTRUCTIONS  iv WARNINGNo one navigational aid should be relied upon for the safety of vessel and crew.The navigator has the responsibility tocheck all aids available to confirmposition. Electronic aids are nota substitute for basic navigationalprinciples and common sense.• This TT automatically tracks    automatically or manually acquired radar   targets and calculates their courses and   speeds, indicating them by vectors. Since   the data generated by the auto plotter   are based on what radar targets are   selected, the radar must always be   optimally tuned for use with the auto   plotter, to ensure required targets will not   be lost or unwanted targets such as sea   returns and noise will not be acquired   and tracked.• A target does not always mean a land-  mass, reef, ships or other surface vessels  but can imply returns from sea surface  and clutter. As the level of clutter changes  with environment, the operator should  properly adjust the A/C SEA, A/C RAIN  and GAIN controls to be sure target  echoes are not eliminated from the  radar screen. CAUTIONThe plotting accuracy and response ofthis TT meets IMO standards.Tracking accuracy is affected by thefollowing:• Tracking accuracy is affected by course   change. One to two minutes is required to   restore vectors to full accuracy after an   abrupt course change. (The actual   amount depends on gyrocompass   specifications.)• The amount of tracking delay is inversely   proportional to the relative speed of the   target. Delay is on the order of 15—30   seconds for high relative speed; 30—60   seconds for low relative speed.• Display accuracy is affected by the   following:   - Echo intensity   - Radar transmission pulsewidth   - Radar bearing error   - Gyrocompass error   - Course change (own ship and target)The data generated by TT, AIS andvideo plotter are intended forreference only.Refer to official nautical charts for detailed and up-to-date information. WARNINGTo avoid electrical shock, do not remove cover. No user-serviceable parts inside.WARNING LABELWarning labels are attached to the equipment. Do not remove any label.If a label is missing or damaged,contact a FURUNO agent or dealerabout replacement.WARNINGRadiation hazard. Only qualified personnel should work inside scanner.Confirm that TX has stopped beforeopening scanner.DISPLAY UNIT, PROCESSOR UNITName:       Warning Label (1)Type:         86-003-1011-1Code No.: 100-236-231ANTENNA UNITName:       Radiation Warning LabelType:         03-142-3201-0Code No.: 100-266-890

  1-11. RADAR OPERATION 1.1  Turning on the Power The [POWER] switch ( ) is located at the left corner of the control unit. Open the POWER switch cover and press the switch to turn on the radar system. To turn off the radar, press the switch again. The screen shows the bearing scale and digital timer approximately 30 seconds after power-on. The timer counts down three minutes of warm-up time. During this period the magnetron (transmitter tube) is warmed for transmission. When the timer has reached 0:00, the indication "ST-BY" appears at the screen center, meaning the radar is now ready to transmit pulses.  In the stand-by condition, markers, rings, map, charts, etc. are not shown. Further, TT and AIS are not shown.  In the warm-up and stand-by conditions, ON TIME and TX TIME count in hours and tenths of hour appear at the screen center.  Note 1: Do not turn the power on directly after it has been turned off. Wait several seconds before you reapply the power, to be sure the radar starts up properly. Note 2: Parameters set on the menus are stored in a non-volatile memory (flash memory), and are preserved when the power is turned off.   1.2 Transmitter ON After the power is turned on and the magnetron has warmed up, ST-BY appears at the screen center, meaning the radar is ready to transmit radar pulses. You may transmit by pressing the [STBY/TX] key on the full keyboard, or use the trackball to select the TX STBY box at the bottom left corner of the display then push the left button (above the trackball). The label at the left-hand side of the guidance box at the bottom right corner of the screen changes from TX to STBY.   GuidanceboxSTBY/TXSTBYTX STBY box Radar display
1. RADAR OPERATION  1-2The radar is initially set to previously used range and pulse length. Other settings such as brilliance levels, VRMs, EBLs and menu option selections are also set to previous settings.    The [STBY/TX] key (or TX STBY box) toggles the radar between STBY and TRANSMIT status. The antenna stops in stand-by and rotates in transmit. The magnetron ages with time resulting in a reduction of output power. Therefore, it is highly recommended that the radar be set to stand-by when not used for an extended period of time.  How to stop antenna rotation Antenna rotation can be stopped. One method is to turn off the antenna switch on the radar. The other method is to stop rotation from the menu. For how to stop rotation from the menu, see the installation manual.  Picture freeze When the picture freezes the picture is not updated. 30 seconds after the picture freezes, the buzzer sounds, the [ALARM ACK] key blinks and the alarm contact signal is output. Reset the power to restore normal operation.  Quick start Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can turn the radar into TRANSMIT condition without three minutes of warm-up. If the [POWER] switch was turned off by mistake or the like and you wish to restart the radar promptly, turn on the [POWER] switch not later than 10 seconds after power-off.  Echo area The echo display area for the B, C and W types is available in three configurations: round, wide, and full screen. You can select a configuration with 7 ECHO AREA on the ECHO menu.

1. RADAR OPERATION  1-71.5  Operation by the On-Screen Boxes All radar functions can be accessed by using the trackball alone. This is done by choosing the appropriate on-screen box with the trackball and operating the trackball module to select item and option. (See section 1.9 for location of all on-screen boxes.) On-screen boxes come in two varieties: Function selection and function selection w/pop-up menu. On-screen boxes of the latter type have "►" at the right side of their boxes, as in the MARK box shown below.  To operate the radar using on-screen boxes, do the following:  1.  Use the trackball to place the trackball marker inside the box desired. Note: The trackball marker changes its configuration according to its location. It is an arrow when placed outside the effective display and a cursor (+) when inside the effective display. See the illustration on the next page for further details.

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°. Graphics and relative and true bearings are also rotated 180°.  True Motion (TM) Land objects and sea are stationary. Requires compass and speed data.  1.12.1  Choosing presentation mode By keyboard Press the [MODE] key consecutively to select presentation mode desired. The PRESENTATION MODE box shows the current presentation mode. (See the illustration below.)  By trackball Left-click the PRESENTATION MODE box at the top left corner of the screen to select a presentation mode. HEAD UP RM** = Other modes:STERN-UP, HEAD UP TB RM, COURSE UP RM,NORTH UP RM, NORTH UP TM PRESENTATION MODE box   Loss of gyrocompass signal When the compass signal is lost, "GYRO" appears in red in the Alert Box, the presentation mode automatically becomes head-up, and TT and AIS targets, map and chart are erased. After restoring the compass signal, "HEADING SET" appears in the Alert Box. Then, stop the alarm with the [ALARM ACK] key or the ALARM ACK box and check the GYRO data.
1. RADAR OPERATION  1-181.12.2  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 ***.*° and the message HDG SIG MISSING appears in red at the lower-right corner of the screen. Heading LineNorth MarkerNote: When display is off-centered,the heading mark appears at 000 degrees. Head-up mode  Course-up mode The course-up mode is an azimuth-stabilized display in which a line connecting the center with the top of the display indicates own ship’s intended course (namely, own ship’s previous heading just before this mode has been selected).  Target pips are painted at their measured distances and in their directions relative to the intended course, which is maintained at the 0-degree position. The heading line moves in accordance with ship’s yawing and course change. This mode is useful to avoid smearing of picture during course change.   Heading LineNorth Marker Course-up mode
1. RADAR OPERATION  1-19Head-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 gyrocompass. If the gyrocompass fails, the bearing scale returns to the state of head-up mode.  North-up mode The north-up mode paints target pips at their measured distances and in their true (heading sensor) directions from own ship, north bearing maintained at the top of the screen. The heading line changes its direction according to the ship’s heading. Requires heading signal.  If the compass fails, the presentation mode changes to head-up and the north marker disappears. Also, the HDG indication shows ***.*°. And the message HDG SIG MISSING appears in red at the lower-right corner of the screen. Heading LineNorth Marker North-up mode
1. RADAR OPERATION  1-20Stern-up mode The stern-up mode rotates the head-up mode picture, relative and true bearings and display graphics 180°. This mode is useful on dual-radar tugboats when backing up; one radar shows head-up and another shows stern-up. To enable the stern-up mode, turn on STERN-UP on the 7 OPERATION menu. Heading LineNorth Marker Stern-up mode
1. RADAR OPERATION  1-21True 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. If COG and SOG (both over the ground) are not available on TM mode, enter the set (tide direction) and drift (tide speed) manually referring to the Tide Table.  When own ship reaches a point corresponding to 50% of the radius of the display, own ship position is automatically reset to a point of 75% radius opposite to the extension of the heading line passing through the display center. You may also reset the own ship symbol manually by pressing the [CU/TM RESET] key, or left-clicking the CU/TM RESET box at the bottom right corner of the display.    If the heading sensor fails, the mode is changed to the head-up and the north marker disappears. The HDG readout shows ***.*° and the message HDG SIG MISSING appears in red at the lower-right corner of the screen.  Note: A part of the bearing scale is drawn differently depending on antenna reference position. ANT: Bearing scale interval is different when display is offcentered. CONN: A part of the bearing scale is not displayed if the conning position is not within the radar display area.

1. RADAR OPERATION  1-261.16 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.  To adjust receiver sensitivity, adjust the gain control so background noise is just visible on the screen.  By keyboard While monitoring the gain level indicator at the top of the screen, operate the [GAIN] control to adjust the sensitivity.  By trackball 1.

1. RADAR OPERATION  1-271.17  Reducing 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 extends. When sea clutter masks the picture, reduce it by the A/C SEA control, either manually or automatically.  Note 1: When both sea clutter and rain clutter are reduced, the sensitivity is decreased more than when only one is adjusted. For that reason adjust them carefully. Note 2: The echo average (see 1.27) is useful for reducing reflections from the sea surface. However, high-speed targets are harder to detect than stationary ones when the echo average is active.   1.17.1  Choosing method of adjustment 1.

Push the left button to display SEA AUTO or SEA MAN as appropriate.  1.17.2  Automatic reduction of sea clutter Auto A/C SEA allows for fine tuning of the A/C SEA circuit, within ±20 dB. Accordingly, with the bar reading set to 100, gain is not lowered to minimum as with manual A/C SEA on close-in ranges. Further, the auto A/C SEA level is low because the average value of the original input echo is low in areas where there are no sea surface reflections. For example, when the ship is alongside a quay and the radar picture shows echoes from both land and sea, you can observe the size of the echoes because the STC curve changes with the size of the echoes.   Note: The auto A/C function can erase weak target echoes. Adjust the control carefully, watching the display.  By keyboard 1.  Select SEA AUTO following the procedure in section 1.17.1. 2.  While observing the A/C SEA level indicator, adjust the A/C SEA with the [A/C SEA] control. 100 levels are available.

While observing the A/C SEA level indicator, roll the scrollwheel downward to increase the A/C SEA or upward to decrease it. 100 levels (0-100) are available.  1.17.3  Manual reduction of sea clutter   The A/C SEA control reduces the amplification of echoes at short ranges (where clutter is the greatest) and progressively increases amplification as the range increases, so amplification will be normal at those ranges where there is no sea clutter.  The proper setting of the A/C SEA should be such that the clutter is broken up into small dots, and small targets become distinguishable. If the setting is set too low, targets will be hidden in the clutter, while if the setting is too high, both sea clutter and targets will disappear from the display. In most cases adjust the control until clutter has disappeared to leeward, but a little is still visible windward. Be careful not to remove all sea clutter, because you may erase weak echoes. Further, the possibility of losing weak echoes is greater when you use both A/C SEA and A/C RAIN to reduce clutter.  A/C SEA adjusted;sea clutter suppressedSea clutter atscreen center By keyboard 1.

AUTO RAIN reduces rain clutter in the picture and A/C RAIN reduces clutter picked up by the antenna.  Note 1: When both sea clutter and rain clutter are reduced the sensitivity is decreased more than when only one is adjusted. For that reason adjust them carefully. Note 2: The echo average (see 1.27) is useful for reducing reflections from the sea surface. However, high-speed targets are harder to detect than stationary ones when the echo average is active.  1.18.1  Automatic reduction of rain clutter Left-click the AUTO RAIN indication at the left side of the screen to select AUTO RAIN setting desired. The higher the number, the greater the degree of rain clutter reduction. OFF turns off the AUTO RAIN feature.  Note: AUTO RAIN can also be controlled from the PICTURE box.  1.18.2  Manual reduction of rain clutter 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. When echoes from precipitation mask solid targets, adjust the A/C RAIN control to split up these unwanted echoes into a speckled pattern, making recognition of solid targets easier. Be careful remove all rain clutter, because you can erase weak echoes. Further, the possibility of losing weak echoes is greater when you use both A/C RAIN and A/C SEA to reduce clutter. Keyboard 1.  Use the trackball to put the cursor in the A/C RAIN level indicator at the top right side of the display. 2.

1. RADAR OPERATION  1-311.19 Measuring 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 get an estimate of the range to a target. The rings are the concentric solid circles on the display. The number of rings is automatically set by the current range scale. The distance between the rings is the range ring interval, and the current interval appears at the upper-left position on the screen. To measure the range to a target with the range rings, count the number of rings between the center of the display and the target.

1. RADAR OPERATION  1-341.20 Measuring Bearing Use the Electronic Bearing Lines (EBLs) to take bearings of targets. There are two EBLs, No. 1 and No. 2. Each EBL is a straight dashed line extending out from the own ship position up to the circumference of the radar picture. The two EBLs can be distinguished from each other by the different lengths of their dashes; the dashes on the No. 2 EBL are longer.  Each EBL carries a range marker, or a short line crossing the EBL at right angles. Its distance from the EBL origin is indicated at the VRM readout whether or not the corresponding VRM is displayed. The range marker changes its position along the EBL with the rotation of the VRM control. To operate this marker, rotate the VRM rotary control on the full keyboard, or put the cursor in the applicable VRM box and roll the scrollwheel.  1.20.1 Measuring bearing By keyboard 1.

1. RADAR OPERATION  1-36 1.21  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 in (a) in the illustration on the next page. If the EBL passes through the sweep origin (own ship) as shown in (b) in the illustration on the next page, the target ship is on a collision course.  1.21.1  How to assess risk of collision by the offset EBL By keyboard 1.  Press the [EBL ON] key to display or activate an EBL (No. 1 or No. 2). 2.  Put the cursor (+) on a target appearing as threatening (A in the illustrated example on the next page) by operating the trackball. 3.  Press the [EBL OFFSET] key, and the origin of the active EBL shifts to the cursor position. Press the [EBL OFFSET key] again to anchor the EBL origin. 4.  After waiting for a few minutes (at least 3 minutes), operate the EBL rotary control until the EBL bisects the target at the new position (A'). The EBL readout shows the target ship's course, which may be true or relative depending on the EBL bearing reference setting. Note: If relative motion is selected, it is also possible to read CPA by using a VRM as shown in left-hand figure at the top of the next page. If the EBL passes through the sweep origin (own ship) as illustrated in the right-hand figure at the top of then next page, the target ship is on a collision course. 5.  To return the EBL origin to the own ship's position, press the [EBL OFFSET] key twice.  By trackball 1.  Display an EBL, following steps 1-3 in "By trackball" in section 1.20.1. 2.

1. RADAR OPERATION  1-391.23 Target Alarm The target alarm serves to alert the navigator to targets (ships, landmasses, etc.) entering a specific area, with audiovisual alarms. CAUTION• The alarm should not be relied upon as   the sole means for detecting possible   collision situations.• A/C SEA, A/C RAIN and GAIN controls  should be properly adjusted to be sure  the alarm system does not overlook  target echoes. The target 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. On any radar type the sector of the zone can be set from 0 to 360 degrees in any direction.  1.23.1  How to set a target alarm The procedure below shows how to set a target alarm using the figure below as an example.  1.

RADAR OPERATION  1-42CursorPut cursor where desiredand do appropriateOFF CENTER procedure        Off-centered display1.24  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.  This feature is not available on the 96 nm range or in the true motion mode.    If the conning position is outside the effective radar display, some parts of the bearing scale are not shown. For details, see section 1.50.  To off-center the radar picture, do the following:  By keyboard 1.  Use the trackball to put the cursor at a position where you wish to move the sweep origin. 2.  Press the [OFF CENTER] key. Then, the sweep origin is off-centered to the cursor position. 3.  To cancel off-centering, press the [OFF CENTER] key again.  By trackball 1.  With the cursor inside the effective display area, roll the scrollwheel to display "OFF CENTER / EXIT" in the guidance box.   2.  Use the trackball to put the cursor where you want to locate the screen center. 3.  Push the left button to off center the sweep origin.   4.  To cancel the off-center function, push the left button when the guidance box reads "OFF CENTER / EXIT."  Note: When the conditions shown below are met, offcenter cannot be cancelled. This is because the radar antenna position is located at a position greater than 75% of the effective radar display.     - Own ship marker is large   - The distance between antenna position and conning position is large   - Short-distance display range. To cancel the offcenter first select a larger range then cancel the offcenter.
1. RADAR OPERATION  1-431.25 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. It compares the received signals over successive transmissions and reduces randomly occurring signals. There are three levels of interference rejection depending on the number of transmissions that are correlated.    Interference To adjust the interference rejector, left-click IR indication at the left side of the screen to select rejection level. "3" provides the highest degree of reduction.    Note: The interference rejector can also be adjusted from the PICTURE box.   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 stretch. Note: The echo stretch magnifies not only small target pips but also returns (clutter) from sea surface, rain and radar interference. For this reason, make sure these types of interference have been sufficiently reduced before activating the echo stretch.  To set echo stretch, left-click the ES indication at the left side of the display. Note: Echo stretch can also be adjusted from the PICTURE box.
1. RADAR OPERATION  1-441.27 Echo Averaging The echo averaging feature effectively reduces 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. If an echo is solid and stable over successive frames, it is presented in its normal intensity. Sea clutter is averaged over successive scans and its brilliance reduced, making it easier to discriminate real targets from sea clutter.  Echo averaging uses scan-to-scan signal correlation technique based on the true motion over the ground of each target. Thus, small stationary targets such as buoys will be shown while reducing random echoes such as sea clutter. True echo averaging is not however effective for picking up small targets running at high speeds over the ground.  Note 1: With echo average active it is harder to detect high-speed targets than stationary ones.  Note 2: Do not use the echo averaging function under heavy pitching and rolling; loss of targets can result. Note 3: Echo averaging can be used without a heading sensor. For further details, contact your dealer. Note 4: Echo averaging requires heading, position and speed data.  Before using the echo averaging function, reduce sea clutter with the A/C SEA control. Leave a little sea clutter on the screen so as not to erase weak targets. Then, do as follows:  Left-click the EAV indication at the left side of the display. OFF:  Echo averaging OFF 1, 2:  Detects targets hidden in sea clutter. "2" is more effective than "1" in detecting targets hidden in strong sea clutter. However, "1" is more effective than "2" in displaying high-speed targets. Select the setting best suited to current conditions. For effective monitoring of high-speed craft, you should use "2" together with Wiper. 3:  Stably displays unstable targets; distinguishes high-speed craft from sea clutter. Note: Echo averaging can also be adjusted from the PICTURE box.

1. RADAR OPERATION  1-461.29 Wiper The wiper feature automatically reduces the brilliance of weak signals (noise, sea clutter, rain clutter, etc.) and unwanted signals such as radar interference to clear the picture of unwanted echoes. Its effect depends on the wiper setting used and whether each averaging is turned on or off, as described below. Echo averaging and wiper states and wiper effect   Wiper setting 1  Wiper setting 2 Echo averaging OFF  Condition A  Condition A Echo averaging ON (1/2/3)  Condition A  Condition B  Condition A: The brilliance of unwanted weak echoes, such as noise, sea clutter and rain clutter, is reduced to clear up the picture. The difference between wiper setting "1" and "2" is that brilliance is lowered more slowly in "2".    Condition B: Echo averaging is automatically activated when the wiper feature is turned on, allowing you to instantly see how the picture is affected with echo averaging turned off and turned on.  To activate the wiper feature, do the following:  1.  Left-click the MENU box to open the menu. 2.  Select 1 [ECHO] to open the ECHO menu.

1. RADAR OPERATION  1-621.35  Automatic Picture Setup According to Navigation Purpose Every time your navigating environment or task changes, you must adjust the radar, which can be a nuisance in a busy situation. Instead of changing radar settings case by case, it is possible to assign the function keys to provide optimum settings for often encountered situations.  The radar's internal computer offers several picture setup options to be assigned to each function key for your specific navigating requirements. For instance, one of the functions is assigned the ship detecting function and labeled SHIP on the on the PICTURE box. By choosing SHIP, the radar will be instantly set for optimum detection of ships.  Four user-programmable setups are also provided (labeled PICTURE1-PICTURE4), so that you may have the radar automatically adjusted to those conditions that are not covered by the provided setup options.  Below are the preset picture setup options provided with this radar. Picture setup options description Label Description Label Description NEAR  Optimum setting for short range detection using a range scale of 3 nm or less on calm seas FAR  Optimum setting for long range detection using a range scale of 6 nm or larger NEAR BUOY Optimum setting for detecting navigation buoys, small vessels and other small surface objects at close range FAR BUOY Optimum setting for detecting navigation buoys, small vessels and other small surface objects at long range HARBOR  Optimum setting for short range navigation in a harbor area, using a range scale of 1.5 nm or less COAST  For coastal navigation using a range scale of 12 nm or less ROUGH SEA Optimum setting for rough weather or heavy rain SHIP  Optimum setting for detecting   vessels  Each picture setup option defines a combination of several radar settings for achieving optimum setup for a particular navigating situation. Those involved are interference rejector, echo stretch, echo average, noise rejector, automatic anti-sea and anti-rain clutters, video contrast, and pulselength and sea and radar conditions.  Adjusting these features from the PICTURE menu changes the original function key settings. To restore the original settings for a particular picture setup option, it is necessary to select the default setting. For this reason, we recommended that you use the user-programmable function sets when frequent adjustment of the radar picture is necessary.

  2-12. 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 reduction and digital quantization. It is a good practice to use a shorter range scale as far as it gives favorable definition or clarity of picture. The IMO Resolution MSC.192(79) requires the minimum range to be less than 40 m, respectively. This series of radars satisfy this requirement.  Maximum range The maximum detecting range of the radar, Rmax, varies considerably depending on several factors such as the height of the antenna above the waterline, the height of the target above the sea, the size, shape and material of the target, and the atmospheric conditions.  Under normal atmospheric conditions, the maximum range is equal to the radar horizon or a little shorter. The radar horizon is longer than the optical one by about 6% because of the diffraction property of the radar signal. The Rmax is given in the following equation. Rmax= 2.2 x ( h1  +h2 )  where Rmax:  radar horizon (nautical miles)    h1: antenna height (m)     h2 : target height (m) Radar horizonOptical horizon  For example, if the height of the antenna above the waterline is 9 meters and the height of the target is 16 meters, the maximum radar range is; Rmax= 2.2 x ( 9   + 16   ) = 2.2 x (3 + 4) = 15.4 nm  It should be noted that the detection range is reduced by precipitation (which absorbs the radar signal).
2. RADAR OBSERVATION  2-2X-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.  Bearing resolution Bearing resolution is the ability of the radar to display as separate pips the echoes received from two targets that are at the same range and close together. It is proportional to the antenna length and reciprocally proportional to the wavelength. The length of the antenna radiator should be selected for a bearing resolution better than 2.5° (IMO Resolution). This condition is normally satisfied with a radiator of 1.2 m (4 ft) or longer in the X-band. The S-band radar requires a radiator of about 12 feet (3.6 m) or longer.  Range resolution Range resolution is the ability to display as separate pips the echoes received from two targets that are on the same bearing and close to each other. This is determined by pulselength only. Practically, a 0.08 microsecond pulse offers the discrimination better than 40 m as do so with all FURUNO radars.    Test targets for determining the range and bearing resolution are radar reflectors having an echoing area of 10 m2.  Bearing accuracy One of the most important features of the radar is how accurately the bearing of a target can be measured. The accuracy of bearing measurement basically depends on the narrowness of the radar beam. However, the bearing is usually taken relative to the ship’s heading, and thus, proper adjustment of the heading line at installation is an important factor in ensuring bearing accuracy. To minimize error when measuring the bearing of a target, put the target echo at the extreme position on the screen by selecting a suitable range.  Range measurement Measurement of the range to a target is also a very important function of the radar. Generally, there are two means of measuring range: the fixed range rings and the variable range marker (VRM). The fixed range rings appear on the screen with a predetermined interval and provide a rough estimate of the range to a target. The variable range marker’s diameter is increased or decreased so that the marker touches the inner edge of the target, allowing the operator to obtain more accurate range measurements.
2. RADAR OBSERVATION  2-32.2 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. A second, a third or more echoes may be observed on the display at double, triple or other multiples of the actual range of the target as shown below. Multiple reflection echoes can be reduced and often removed by decreasing the gain (sensitivity) or properly adjusting the A/C SEA control. Own shipTargetTr u eechoMultiple echo Multiple echoes Sidelobe echoes Every time the radar pulse is transmitted, some radiation escapes on each side of the beam, called "sidelobes." If a target exists where it can be detected by the side lobes as well as the main lobe, the side echoes may be represented on both sides of the true echo at the same range. Side lobes show usually only on short ranges and from strong targets. They can be reduced through careful reduction of the gain or proper adjustment of the A/C SEA control. Target B(True)Target B(Spurious)Target A Sidelobe echoes
2. RADAR OBSERVATION  2-4Virtual 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  2-52.3  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. This process is repeated for a total of twelve complete cycles. At some point in each sweep, the SART frequency will match that of the interrogating radar and be within the pass band of the radar receiver. If the SART is within range, the frequency match during each of the 12 slow sweeps will produce a response on the radar display, thus a line of 12 dots equally spaced by about 0.64 nautical miles will be shown.  When the radar to the SART is reduced to about 1 nm, the radar display my show also the 12 responses generated during the fast sweeps. These additional dot responses, which also are equally spaced by 0.64 nautical miles, will be interspersed with the original line of 12 dots. They will appear slightly weaker and smaller than the original dots. 9500 MHz9200 MHzRadar antennabeamwidthScreen A: When SART                  is distantScreen B: When SART                  is close Lines of 12 dots are displayed in concentric arcs.Echo from SARTPosition ofSARTOwn shipposition Own shippositionSART marklengthRadar receiverbandwidthSweep time7.5 μs 95 μs Sweep startHigh speed sweep signalLow speed sweep signal24 NM 1.5 NMPosition ofSARTEcho fromSART SART
2. RADAR OBSERVATION  2-62.3.2  Showing SART marks on the radar display This radar is equipped with a feature that 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. When the radar approaches the SART in operation, the SART marks will enlarge to large arcs, blurring a large part of the screen.   To set up for SART detection do the following:  1.

2. RADAR OBSERVATION  2-72.3.3  General remarks on receiving SARTs 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.  Radar bandwidth This is normally matched to the radar pulselength and is usually switched with the range scale and the associated pulselength. Narrow bandwidths of 3-5 MHz are used with long pulses on long range scales and wide bandwidths of 10-25 MHz with short pulses on short ranges.  A radar bandwidth of less than 5 MHz will attenuate the SART signal slightly, so it is preferable to use a medium bandwidth to ensure optimum detection of the SART.   Radar side lobes As the SART is approached, side lobes from the radar antenna may show the SART responses as a series of arcs or concentric rings. These can be removed by the use of the anti-clutter sea control although it may be operationally useful to observe the side lobes as they may be easier to detect in clutter conditions and also they will confirm that the SART is near to own ship.  Note: SART information excerpted from IMO SN/Circ 197 OPERATION OF MARINE RADAR FOR SART DETECTION.
2. RADAR OBSERVATION  2-82.4 RACON A RACON is a radar beacon that 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. RACON RACON   2.5 Radar Target Enhancer (RTE) An RTE is a radar transponder is mounted on navigation buoys and masts of small crafts to significantly improve their detection by radar. Unlike a SART or RACON, which are passive, the RTE receives a radar signal, amplifies it and re-transmits it, with the intention of making the target's signal look larger on a radar display. The RTE is available in X-band and S-band types.
  3-13. TARGET TRACKING (TT) 3.1 Usage Precautions WARNINGNo one navigational aid should be relied upon for the safety of vessel and crew.The navigator has the responsibility tocheck all aids available to confirmposition. Electronic aids are nota substitute for basic navigationalprinciples and common sense.• This TT automatically tracks    automatically or manually acquired radar   targets and calculates their courses and   speeds, indicating them by vectors. Since   the data generated by the auto plotter   are based on what radar targets are   selected, the radar must always be   optimally tuned for use with the auto   plotter, to ensure required targets will not   be lost or unwanted targets such as sea   returns and noise will not be acquired   and tracked.• A target does not always mean a land-  mass, reef, ships or other surface vessels  but can imply returns from sea surface  and clutter. As the level of clutter changes  with environment, the operator should  properly adjust the A/C SEA, A/C RAIN  and GAIN controls to be sure target  echoes are not eliminated from the  radar screen. CAUTIONThe plotting accuracy and response ofthis TT meets IMO standards.Tracking accuracy is affected by thefollowing:• Tracking accuracy is affected by course   change. One to two minutes is required to   restore vectors to full accuracy after an   abrupt course change. (The actual   amount depends on gyrocompass   specifications.)• The amount of tracking delay is inversely   proportional to the relative speed of the   target. Delay is on the order of 15—30   seconds for high relative speed; 30—60   seconds for low relative speed.• Display accuracy is affected by the   following:   - Echo intensity   - Radar transmission pulsewidth   - Radar bearing error   - Gyrocompass error   - Course change (own ship and target)The data generated by TT, AIS andvideo plotter are intended forreference only.Refer to official nautical charts for detailed and up-to-date information.

For echo-referenced speed input follow the procedure below.  3.4.1  Echo-referenced speed input The use of echo-referenced speed is recommended when: •  The speed log is not operating properly or not connected to the radar. •  The vessel has no device (doppler sonar, speed log, etc.) that can measure ship's bow-stern, port-starboard movement. If you select echo-referenced speed, the TT calculates own ship's speed relative to a fixed reference target. The number of targets may be R1, R2 or R3. When a plural of objects are selected, the mean value is used, for stabilization and speed.   1.

Notes on speed input by reference target •  Reference targets are only used for the calculation of true speed. •  Do not use reference target generated true speed to calculate relative speed. Relative speed data is not accurate because response to speed change is slow, hampering the TT's ability to accurately judge the possibility of collision. •  Select a stationary target as a reference target to calculate own ship speed as ground tracking speed. Do not choose a moving target as a reference target. A moving target produces error in the vector for TT and AIS, which results in wrong collision avoidance information. Further, an unstable stationary target produces inaccurate speed data and the target itself may become lost.   •  When a reference target is lost or goes out of the acquisition range, that reference target mark blinks and the indication "REF TARGET LOST" appears in the alarm box. If all reference targets are lost, the speed indication reads "*.*" Select a different reference target if currently selected one is lost. •  When all targets are deleted, the reference target mark is also deleted and the target-based speed becomes invalid. The speed is indicated as BTREF where BT means Bottom Track (speed over ground). •  Reference targets may be marked with a vector. This can be done with 3 REF TARGET VECTOR on the TT TARGET menu. •  Loss of reference target will affect the calculation of true speed and true course of targets. Further, own ship speed will be inaccurate.    Canceling echo-referenced speed input Open the SPD menu, referring to section 1.13, and set 1 SHIP SPEED to LOG, NAV or MANUAL as appropriate.

3. TARGET TRACKING (TT)  3-8The plotting symbol is drawn by broken lines during the initial acquisition stage. A vector appears in about one minute after acquisition indicating the target's motion trend. If the target is consistently detected for three minutes, the plotting symbol changes to a solid circle. If acquisition fails, the target plotting symbol blinks and disappears shortly.  TT Symbol  Meaning  Immediately after acquisition, this plotting symbol is shown in broken lines.  Within one minute after acquisition, a vector appears to show a trend of movement.  Within three minutes after acquisition, the plotting symbol changes to a small circle, indicating steady-state tracking condition.  Note 1: For successful acquisition, the target to be acquired should be within 0.1 to 24 nm (or 32 nm, depending on initial setting) from own ship and not obscured by sea or rain clutter. Note 2: When the capacity for manual acquisition is reached, the message "TARGET FULL(MAN)" is displayed at the screen bottom. Cancel tracking of non-threatening targets if you wish to acquire additional targets manually. Note 3: Target number is normally not shown. On the A, B, C and W type radars it appears when the cursor is placed on a TT symbol.  CAUTIONTarget SwapWhen a target being tracked nears anothertarget being tracked, the targets may be"swapped". When two targets acquiredeither automatically or manually come closeto each other, one of the two may becomea Lost Target.

3. TARGET TRACKING (TT)  3-213.13  TT Collision Alarm (CPA, TCPA) The TT continuously monitors the predicted range at the Closest Point of Approach (CPA) and predicted time to CPA (TCPA) of each TT. When the predicted CPA of any TT becomes smaller than a preset CPA range and its predicted TCPA less than a preset TCPA limit, the audio alarm sounds and TT COLLISION appears (in red) in the Alert Box. In addition, the symbol of the offending TT is red and flashes together with its vector.  This feature, when used correctly, helps prevent the risk of collision by alerting you to threatening targets. It is important that GAIN, A/C SEA, A/C RAIN and other radar controls are properly adjusted.  CPA and TCPA ranges must be set up properly taking into consideration the size, tonnage, speed, turning performance and other characteristics of own ship.  The reference point for CPA and TCPA calculation may be selected from antenna position or conning position. For further details, see section 1.50.  3.13.1  Setting the CPA and TCPA ranges To set the CPA and TCPA ranges, do the following:  1.  Left-click CPA LIMIT box to show the CPA and TCPA boxes.

The warning label TT COLLISION and the flashing of the triangle plotting symbol and vector remain in the Alert Box until the dangerous situation is gone or you intentionally terminate tracking of the target.  Note that when the TT COLLISION alarm is generated the AIS display is automatically turned on.   3.14 Acquisition Zone The acquisition zone functions both to alert you targets in a specific area and acts as an automatic acquisition area when automatic target acquisition is active. Any targets entering the zone will be automatically acquired.  When a target enters an acquisition zone, the buzzer sounds and the indication TT NEW TARGET (or AIS NEW TARGET) appears (in red) in the Alert Box. The symbol of the offending target is red and flashing. Further, the AIS display is automatically turned on if it is off.    3.14.1  Activating an acquisition zone One or two acquisition zones may be activated. The No. 1 acquisition zone is available between 3 and 6 nm and the No. 2 acquisition zone can be set anywhere when the No. 1 zone is already in use.

3. TARGET TRACKING (TT)  3-263.16 Trial Maneuver The trial maneuver feature simulates the effect on all tracked targets against own ship's maneuver. Enter your expected course, speed and time-to-maneuver to find the relationship between your ship and other ships against your planned maneuver. Further, set CPA and TCPA values to find possible collision situations.  Enter various courses and speeds until a dangerous situation is resolved. The trial manuever feature proceeds without interrupting the updating of target information.   For more accurate results, use relative motion and sea stabilization (ground tracking) and be sure that own ship's characteristics such as acceleration and turning performance have been properly set in the initial settings during the installation. Take into consideration own ship's maneuvering characteristics such as rudder delay, turning delay and acceleration delay. This is particularly important on large vessels.  3.16.1  Types of trial maneuvers There are two types of trial maneuvers: static and dynamic.  Dynamic trial maneuver A dynamic trial maneuver displays predicted positions of the tracked targets and own ship. You enter own ship's intended speed and course with a certain "delay time." Assuming that all tracked targets maintain their present speeds and courses, the targets' and own ship's future movements are simulated in one-second increments indicating their predicted positions in 30-second intervals as illustrated below.  The delay time represents the time lag from the present time to the time when own ship will actually start to change her speed and/or course. How much the delay is set the situation starts immediately and is updated every 0.5 seconds.  In the example shown below, own ship will advance straight ahead (even after a maneuver) for a delay time of 2:30 then alters speed and course until operator-specified intended speed and course are achieved (position OS5 in this example). OS6 and OS7 show changes in course and speed and OS8 show that the ship has completed course and speed adjustments.   Delay time = 2 m 30 s.Present own ship position

Put the cursor in any one of the four trial maneuver related boxes and operate applicable control. 13. Select TRIAL SET. Push the left button or the scrollwheel. The TRIAL box shows "TRAIL 00:00" (00:00 is trial maneuver time).  The time indication depends on trial mode: Dynamic mode: The position of your ship and tracked targets is updated and displayed every 30 seconds. Static mode: The position of your ship and tracked targets when set course and speed are reached are displayed. The progress time until the position is reached is indicated on the display. The trial time can be changed from the Trial Time box. Put the cursor in the Trial Time box and roll the scrollwheel. The position of targets at the end of selected time is shown. Increase or decrease the time to get a safe manuever. When the cursor is removed from the box the original positions of your ship and tracked targets are restored. If a manuever is unsafe, change speed, course and delay until it is safe. The trial maneuver takes place with the letter "T" displayed at the bottom of the screen. The time appears at the top right side of the display. If any tracked target is predicted to be on a collision course with own ship (that is, the target ship comes within preset CPA/TCPA limits), the target plotting symbol is red. If this happens, change own ship's trial speed, course or delay time to obtain a safe maneuver.   3.16.3  Terminating a trial maneuver A trial maneuver is automatically terminated at the end of the fixed time and the normal radar display is restored. The time of termination depends on the trial mode as follows: Dynamic mode: The trial is terminated when 60 minutes is shown in the Trial Time Box. Static mode: The trial is terminated when there is no key operation within one minute.  To terminate the trial maneuver manually, put the cursor in the Trial Time box then push the left button to show TRAIL OFF in the box.  Note: To stop the trial maneuver, select OFF at step 5 in the procedure in section 3.16.2.

3. TARGET TRACKING (TT)  3-323.18  Criteria for Selecting Targets for Tracking The FURUNO TT 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. All smaller ship-sized echoes that are less than this dimension, are further analyzed and regarded as ships and displayed as small circles superimposed over the video echo.  When a target is first displayed, it is shown as having zero true speed but develops a course vector as more information is collected. In accordance with the International Marine Organization Automatic Radar Plotting Aid (IMO TT) requirements, an indication of the motion trend should be available within 20 scans of antenna and full vector accuracy within 60 scans. The FURUNO TTs comply with these requirements.  Acquisition and tracking A target which is hit by five consecutive radar pulses, is detected as a radar echo. Manual acquisition is done by designating a detected echo with the trackball. Automatic acquisition is done in the acquisition areas when a target is detected 5-7 times continuously depending upon the congestion. Tracking is achieved when the target is clearly distinguishable on the display for 5 out of 10 consecutive scans, whether acquired automatically or manually. Required tracking facilities are available within 0.1-32 nm on range scales including 3, 6, 12 nm, full plotting information is available within one scan when the range scale has been changed.  Targets not detected in five consecutive scans become "lost targets."  Quantization The entire picture is converted to a digital from called "Quantized Video." A sweep range is divided into small segments and each range element is "1" if there is radar echo return above a threshold level, or "0" if there is no return.  The digital radar signal is then analyzed by a ship-sized echo discriminator. As the antenna scans, if there are five consecutive radar pulses with 1’s indicating an echo presence at the exact same range, a target "start" is initiated. Since receiver noise is random, it is not three-bang correlated, and it is filtered out and not classified as an echo.  The same is true of radar interference. Electronic circuits track both the closet and most distant edges of the echo. At the end of the scanning of the echo, the discriminator indicates the measured maximum range extent and total angular extent subtended by the echo. If the echo is larger than a ship-sized echo in range extent and/or angular width, adjusted as a function of range, it is declared to be a coastline and the closet edge is put into memory as a map of the area.
3. TARGET TRACKING (TT)  3-33This 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. When it is determined to be as consistent as a real target, automatic acquisition occurs and tracking is initiated. Continued tracking and subsequent calculation develop the relative course and speed of the target.  The true course and speed of own ship are computed from own ship's gyro and speed inputs, and the resulting course and speed of each tracked target is easily computed by vector summing of the relative motion with own ship’s course and speed. The resulting true or relative vector is displayed for each of the tracked targets. This process is updated continually for each target on every scan of the radar.  Qualitative description of tracking error The FURUNO TT's accuracy complies with or exceed IMO standards.  Own ship maneuvers For slow turns there is no effect. For very high turning rates (greater than 150°/minute, depending on gyro), there is some influence on all tracked targets that lasts for a minute or two then all tracked targets revert to full accuracy.  Other ship maneuvers Target ship courses, lag 15 to 30 seconds at high relative speed, or 3 to 6 seconds at low (near 0) relative speed. It is less accurate during a turn due to lag, but accuracy recovers quickly.
3. TARGET TRACKING (TT)  3-343.19 Factors Affecting TT 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. If heavy clutter still exists, switch to manual acquisition. Accuracy can be affected.  Low clouds Usually no affect. If necessary, adjust the A/C RAIN control.  Non-synchronous emissions No effect.  Low gain Insufficient or low radar receiver gain will result in some targets not being acquired at long distance. TT display will be missing on one or more targets that could only be visible if the radar sensitivity control (GAIN control) were increased.  The setting of the correct radar receiver gain is not critical but the target should be on the radar PPI and be clearly visible and well defined.  Manual acquisition is done if a target is positively displayed more than once. Automatic acquisition is done when the target is detected 5-7 times continuously. Tracking is achieved when the target is detected five times (not necessarily continuously) out of 10 scans. If not detected six times out of 10 scans, the target will become a "lost target." The TT will acquire a radar echo that is present once in every six antenna scans and continue tracking if 1 in 10.  Second trace echoes When the radar beam is super refracted, strong echoes may be received at such long ranges that they appear on a different timebase sweep than the transmitted pulse. This gives an incorrect range indication. Second and third trace echoes can be tracked if they are consistent enough to meet acquisition and tracking criteria but target course and speed data will be in error.
3. TARGET TRACKING (TT)  3-35Blind 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 TT system will lose track of targets shortly after they are lost on the radar picture and if they remain in a blind zone. These targets will however be acquired and tracked when they pass out of the blind zone and again present normal radar echo. The angular width and bearing of any shadow sector should be determined for their influence on the radar. In certain cases false echoes in the shadow sector cause the TT system to acquire, track, and vector them. Shadow sectors should be avoided.  Indirect echoes A target at close range is usually picked up directly, but it can also be received as reflection from a large, flat surface. This will result in the radar presenting two or more echoes on the display, each at a different range. The TT can acquire and track the false echo if it is detected by five consecutive scans. Reduction in radar gain can eliminate the multiple echoing but care should be taken as range detection also will be reduced.  Radar interference If interference is extreme due to another radar operating at close range, spiral "dotting" and/or false targets may appear momentarily. The interference rejector can clear the display.  To receive radar beacon or SART signals, turn on "SART" in the ECHO menu.

  4-14. 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 TT information.    For the IMO specification, position data must be fixed by WGS-84 geodetic datum and speed input must be ground tracking. If other type of datum is input, the error message "DATUM" appears and the AIS feature is inoperative. This restriction does not apply to other types.  When AIS is active, MANUAL and REF in the speed source selection window are shown in gray to indicate they are not available for selection.

  5-15.  VIDEO PLOTTER OPERATION 5.1 General The video plotter does the following functions: •  Plots own and other ships’ tracks. (Plotting of other ships’ tracks not available on IMO type.) •  Enters waypoints, nav lines and marks. •  Creates and displays radar maps. •  Records data onto memory cards (optional card interface required). •  It uses two types of memory cards, a memory card (RAM card) for storing own ship and other ship’s tracks and marks, and a digital chart card (ROM card). •  30 nav lines may be stored and each line may contain up to 30 waypoints. One nav line may be shown on the display. 200 waypoints are available. Own ship and other ship tracks may be stored at a selected interval.   •  Charts (A, B, C and W types) are superimposed on the radar picture without disturbing the radar observation. The chart area is dependent on the radar range in use.     5.2 Display Modes This radar has display modes as follows. •  IMO, A type:  Radar, Radar + Plotter, Anchor Watch •  B, C, W type:  Radar, Radar + Plotter, Plotter    Use the DISPLAY MODE box to select a mode. (When the video plotter mode is displayed more than five seconds, the radar automatically goes into standby.)  Note 1: Display mode cannot be selected when the menu is open. Close the menu to select a display mode. Note 2: IMO type radar can display own ship’s track and L/L grid on the +PLOTTER display. Note 3: The anchor watch, as well as AIS, is active in standby.

MAINTENANCE, TROUBLESHOOTING  6-8Advanced troubleshooting (con’t) Problem  Probable causes or check points Remedy Marks, indications and noise appear but no echo (Transmission leak representing own ship position is absent) 1) TX high voltage protection circuit has activated.  2) Magnetron   3) Modulator board 4) SPU board 1) Reset power to restore normal operation.   2) Check magnetron current. Replace magnetron.    3) Replace modulator board. 4) Replace SPU board. Picture not updated or picture freeze-up 1) Bearing signal generator board (in antenna unit)  2) SPU board 3) Video freeze-up 1) Check the connection of signal cables.  2) Replace SPU board. 3) Turn off and on the radar. Incorrect orientation of picture 1) SPU board   2) Gyro interface 1) The message HDG SIG MISSING appears when the heading pulse is not received during transmitting. 2) Replace the gyro interface. Cannot operate radar from on-screen boxes SPU Board  Replace SPU Board. Radar is properly tuned but poor sensitivity 1) Deteriorated magnetron   2) Detuned MIC    3) Dirt on radiator face 4) Water ingress to the         waveguide or other    feeder line 5) Second trace echo         rejection is ON 1) With the radar transmitting on 48 nmrange, check magnetron current. If current is below normal, magnetron may be defective. Replace it. 2) Check MIC detecting current. If it is below normal value, MIC may have become detuned. MIC must be tuned. 3) Clean the radiator surface. 4) Remove water from the feeder line.   5) Disable the second-trace echo           rejector referring to section 1.38. Range changed but radar picture not changing 1) Defective range key    2) SPU board 3) Video freeze up 1) Try to hit RANGE [+] and [-] keys several times. If unsuccessful, replacement of keypad may be required. 2) Replace SPU board. 3) Turn off and on radar. (Continued on next page)

APPENDIX  AP-46 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. The table below shows the longitude error, represented from 0° to 90° at 96 nm from the radar center (own ship). 62°N°N60°N135°E°E96 nmθReal cursor positionCursor positionindicated139°ELATReal cursor positionR: ErrorCursor positionindicatedOS position Distance error in direction of longitude due to latitude
