3. TARGET TRACKING (TT)3-123.10.2 How to change the vector length (time)The vector time provides an estimation of the target’s vector and can be adjusted as follows:Place the cursor on the vector time indication in the [Vector] box, then press the left button. The vector time cycles through the following settings with each press of the left button.[6min]  [10min]  [20min]  [30min]  [45min]  [60min]  [30sec]  [1min]  [3min]  [5min]  [6min]...The vector tip shows an estimated position of the target after the selected vector time elapses. It can be valuable to extend the vector length to evaluate the risk of collision with any target.3.11 Past Position DisplayThe past position display shows equally time-spaced dots marking the past positions of any targets being tracked.A new dot is added every minute (or at other preset time intervals) until the preset number is reached. If a target changes its speed, the spacing will be uneven. If it changes the course, its plotted course will not be a straight line.Past position orientation, true or relative, is controlled with [TRAIL MODE] in the [TRAIL] context menu. To adjust the trail orientation, see paragraph 1.36.1.3.11.1 How to display past position points and select the past position plotting intervalPlace the cursor on the [PAST POSN] time indication in the [PAST POSN] box, then press the left button. The past position points are displayed and their plotting interval changes with each press of the left button, as shown below.[OFF]  [30sec]  [1min]  [2min]  [3min]  [6min]  [OFF]...3.11.2 How to select the number of past position points to be displayed1. Open the [MAIN MENU].2. Select [TT•AIS], then press the ADJUST knob.3. Select [TT•AIS SYMBOL], then press the ADJUST knob.4. Select [TT•AIS PAST POSN POINTS], then press the ADJUST knob.5.

3. TARGET TRACKING (TT)3-133.12 Set and DriftSet, the direction in which a water current flows, can be manually entered in 0.1-degree steps. Drift, also known as “Rate”, or the speed of the current, can also be entered manually in 0.1-knot steps.When course through water and speed through water are available, activate set and drift to get course over ground and speed over ground.Set and drift corrections are beneficial for increasing the accuracy of vectors and tar-get data. Refer to the tide table on board the ship for setting information. These values are applied to all targets. If stationary targets have vectors, set and drift values should be adjusted until they lose vectors.To enter set and drift do the following:1. Select the [SPD] menu box, then press the right button. The [SHIP SPEED MENU] is displayed.2. Select [SET DRIFT], then press the ADJUST knob.3. Select [ON], then press the ADJUST knob. The setting can now be adjusted and [SET] is selected.4. Rotate the ADJUST knob to select the appropriate setting (Setting range: 000.0° to 359.9°), then press the ADJUST knob. The [DRIFT] setting is now selected.5. Rotate the ADJUST knob to select the appropriate setting (Setting range: 00.0kn to 19.9kn), then press the ADJUST knob.6. Close the menu.Note 1: Set and drift are available when using manually input speed, speed through the water. The speed source is shown as "WTC" (Water Tracking Count).Note 2: Set and drift should be checked periodically for correctness.Note 3: When speed data input from the position sensor is valid, set and drift is not adjustable.
3. TARGET TRACKING (TT)3-143.13 Collision Alarm (CPA, TCPA)This radar calculates CPA and TCPA by using own ship and relative target positions.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, ton-nage, speed, turning performance and other characteristics of own ship.The reference point for CPA and TCPA calculation can be selected from antenna position or conning position. For further details, see section 1.47.3.13.1 How to set the CPA and TCPA rangesCPA and TCPA ranges can be adjusted from the appropriate indication in the [TT] box.1. Place the cursor on the indication you wish to adjust.2. Press the left button, or rotate the ADJUST knob, to adjust the settings as required. The settings options are outlined in the table below.3.13.2 How to acknowledge the TT collision alarmPress the key on the control unit, or select the [ALERT] box with the Touchpad then press the left button to acknowledge the alarm and silence the buzzer. The alert "TT COLLISION" and the flashing of the 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.Indication Key Settings optionsCPA Left button 0.5, 1, 1.5, 2, 3, 4, 5, 6 (nm)ADJUST knob 0.1-20 (nm), 0-10 nm in 0.1 nm increments, 10 nm increments thereafterTCPA Left button 1, 2, 3, 4, 5, 6, 12, 15 (minutes)ADJUST knob 1-60 minutes, 1-minute incrementsCAUTIONCPA/TCPA AlarmThe CPA and TCPA alarm feature shouldnever be relied upon as the sole means fordetecting the risk of collision.The navigatoris not relieved of the responsibility to keepvisual lookout for avoiding collisions,whether or not the radar or other plottingaid is in use.CPA settingTCPA setting
3. TARGET TRACKING (TT)3-153.14 Acquisition ZoneThe 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 yellow-orange) 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.There are two types of acquisition zones available, arc and polygon, however, AZ1 can only be set as an arc.Note: The [AZ1] and [AZ2] boxes are not displayed when the setting for [AZ/ALR SELECT] in the [TT•AIS] menu is set to [TARGET ALARM ZONE].3.14.1 How to activate the first acquisition zone (AZ1)The No. 1 acquisition zone is available between 3 and 6 nm The TT/AIS acquisition zone’s lines are white and dashed so as to distinguish them from the radar target alarm.The procedure below shows how to set AZ1, using the example at the bottom of the page.1.

3. TARGET TRACKING (TT)3-193.16 TT Simulation ModeYou can simulate the risk of a collision by using the TT simulation mode. The test can be terminated at any time by pressing the key.1. Open the [MAIN MENU].2. Select [INTIAL SETTING], then press the ADJUST knob.3. Select [TEST], then press the ADJUST knob.4. Select [TT TEST], then press the ADJUST knob.The normal operation is suspended then three simulated targets appear on the dis-play.The indication "S" appears at the bottom of the effective display area during the sim-ulation mode. The simulation may be terminated any time by going to the STBY mode.Three simulated targets move as the following table. The simulated target is automat-ically generated with the relative movement in the following table based on own ship's movement at the start of simulation mode.Note: If own ship moves after the start of simulation mode, the movement of the sim-ulated target is not matched with the values in the following table.Place the cursor on a target, then press the key to display the target data.Acquire the simulated targets after the TT simulation mode is performed. The tracking state changes from unstable to stable and the vector appears. You can simulate the movement of each function with changing true/relative vector, stabilization through the water/over the ground, range or length of vector.Repeat the check for all targets.Range (R) Bearing (R) Speed (R) Course (R) CPA TCPATarget 01 9.5 NM 270.0° 20.0 kn 90.0° 0.0 NM 28.5 minTarget 02 1.1 NM 333.0° 10.2 kn 90.2° 1.0 NM 2.9 minTarget 03 9.3 NM 45.0° 19.9 kn 225.1° 0.0 NM 28.0 minS010302
3. TARGET TRACKING (TT)3-203.17 Criteria for Tracking Target SelectionThe 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 criteriaA 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.Automat-ic acquisition is done in the acquisition areas when a target is detected 5-7 times con-tinuously depending upon the congestion. Tracking is achieved 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”.QuantizationThe 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.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. 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.
3. TARGET TRACKING (TT)3-21The 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 errorThe FURUNO TT's accuracy complies with or exceed IMO standards.Own ship maneuversFor 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 maneuversTarget 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.3.18 Factors Affecting TT FunctionsLow gainInsufficient 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 vis-ible 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.Sea returnsIf 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 snowClutter 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 cloudsUsually no affect. If necessary, adjust the A/C RAIN.
3. TARGET TRACKING (TT)3-22Non-synchronous emissionsNo effect.Second trace echoesWhen 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.Blind and shadow sectorsRadar shadow or blind areas caused by obstructions aboard ship, for example, fun-nels 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 an-gular 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 echoesA 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 interferenceIf 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 OPERATIONAn AIS transponder can be connected to this radar to overlay AIS targets on the radar display. The radar can store up to 1,000 AIS targets in its storage buffer. When this buffer becomes full of AIS targets, the Alert 190 "TARGET CAPACITY (AIS CAPACITY FULL)" is generated to alert you to full storage buffer. The storage buffer contains automatic dead reckoning for all AIS targets, which is based on reported Speed Over the Ground (SOG), Course Over the Ground (COG), Rate Of Turn (ROT) and heading. The storage buffer also contains calculation of range, bearing, CPA, TCPA, etc. The CPA and TCPA limits set for dangerous targets are common for TT and AIS targets.This radar can activate 40 AIS targets. The Alert 190 "TARGET CAPACITY (AIS CAPACITY FULL)" is generated when 40 AIS targets are activated.This radar can display a maximum of 300 AIS targets. The Alert 190 "TARGET CAPACITY (AIS CAPACITY FULL)" is generated when 300 AIS targets, which includes both activated and sleeping targets, are displayed.The frequency for update of AIS transponder-sent data depends on speed and course of tracked AIS target. The table below shows the IMO standardized reporting rates for the AIS transponder. Based on the table below, the radar defines which AIS targets are in tracking or lost. When you acknowledge a lost target alert, the corresponding AIS symbol will be removed from the display.An AIS transponder “sees” all ships fitted with an AIS transponder belonging to either a Class A or Class B AIS. Additionally, the AIS transponder receives messages from ships and non-ships (AIS SAR aircraft, AIS aid to navigation, AIS base station, and AIS search and rescue transmitter).Type of ShipIMOnominalreportingintervalLost target indication (reportinginterval >)Class A: Navigation status is “anchor” or “not under command” or “moored” or “aground”, and SOG  3kn3 min 10 minClass A: Navigation status is “anchor” or “not under command” or “moored” or “aground”, and SOG > 3kn10 s 50 sClass A: 0kn  SOG < 14kn 10 s 50 sClass A: 14kn  SOG  23kn 6 s 30 sClass A: SOG > 23kn 2 s 10 sClass B: “CS” SOG < 2kn 3 min 10 minClass B: “CS” SOG  2kn 30 s 150 sClass B: “SO” 0 kn  SOG < 2kn 3 min 10 minClass B: “SO” 2 kn  SOG < 14kn 30 s 150 sClass B: “SO” 14 kn  SOG  23kn 15 s 75 sClass B: “SO” SOG > 23kn 5 s 25 sClass A and Class B: no SOG available N/A 10 minAIS SAR aircraft 10 s 50 sAIS aid to navigation 3 min 10 minAIS base station 10 s 50 sAIS search and rescue transponder N/A 10 min
4. AIS OPERATION4-24.1 Controls for AIS• TGT ACQ: Displays the selected target’s data.• TGT CANCEL: Sleeps the cursor-selected target.These functions, along with other AIS functions, can also be accessed from the [CURSOR] menu (See section 1.7).There can be several hundreds or several thousands of AIS targets, and of those only a few will be significant for your ship. To remove unnecessary AIS targets from the radar display, the feature “active and sleeping AIS targets” is available. Initially any new AIS target received by an AIS transponder is not active (=“sleeping”). Such sleeping targets are shown with a small triangle. The operator can pick any AIS target and change it from sleeping to active. Active AIS targets are shown with a large triangle with speed vector, headline, ROT indicator, etc. Further, the operator can pick active AIS targets and change their status to sleeping.An indication of AIS target activated capacity limit is given well before it is reached. When 95% of 40 targets are activated, the Alert 190 "TARGET CAPACITY (AIS ACITVATE 95%)" appears. When 40 targets are activated, the Alert 190 "TARGET CAPACITY (AIS ACTIVATE FULL)" appears.An indication of AIS target display capacity limit is given well before it is reached. When 95% of 300 targets are displayed, the Alert 190 "TARGET CAPACITY (AIS ACTIVATE 95%)" appears. When 300 targets are displayed, the Alert 190 "TARGET CAPACITY (AIS DISPLAY FULL)" appears.An indication of AIS target processing capacity limit is given well before it is reached. The Alert 190 "TARGET CAPACITY (AIS CAPACITY FULL)" appears when 1,000 targets are in the storage buffer.This radar generates AIS-related alerts. These are Alert 191 "CPA/TCPA (AIS COLLISION" and Alert 193 "LOST TARGET (AIS LOST)". Only active AIS targets generate alerts. The operator can activate or sleep AIS target alerts as desired. The feature “active and sleeping AIS targets” is very effective for focusing on only those AIS targets that need supervision. This radar further eases the task of the operator by automatically changing non-active targets to active targets, if their CPA and TCPA are within a preset limit.Displays AIS target data Cancel targetSelect the AIS box, then press the left button to cycle through AIS display modes.DISP OFF: Hides AIS targetsDISP FILT: Displays a filtered selection of AIS targetsDISP ALL: Displays all AIS targetsFUNC OFF: Deactivates the AIS function

AP-5APPENDIX 2 LONGITUDE ERROR TABLE (96 NM 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 nmqReal cursor positionCursor positionindicated139°ELATReal cursor positionR: ErrorCursor positionindicatedOS position0.2256 0.4444 0.6496 0.8350 0.9950 1.1248 1.2202 1.2786 1.29800.21980213 0.43290201 0.632803 0.8134132 0.96923215 1.09551918 1.1884382 1.24517456 1.264020370.21229339 0.41810678 0.61115946 0.78556318 0.93600295 1.05790007 1.14755221 1.20224625 1.220340420.20316898 0.40012949 0.58486463 0.75173456 0.89565021 1.0122297 1.09793265 1.15016811 1.167372940.19249832 0.37910698 0.55411863 0.71218478 0.84848102 0.95885565 1.03998717 1.08933651 1.105521050.18036264 0.35519924 0.51915545 0.66721485 0.79485438 0.89818413 0.97406698 1.02021439 1.035255470.16685429 0.32858822 0.48024119 0.61716701 0.73517843 0.83067689 0.90076355 0.94332783 0.957110980.15207608 0.29947644 0.437672 0.56242216 0.66990732 0.7568477 0.82060477 0.85926197 0.871682290.13614047 0.26808546 0.39177186 0.53339693 0.59953781 0.67725844 0.73420069 0.76865661 0.779619570.11916876 0.2346542 0.3428901 0.44054055 0.52460545 0.59251483 0.6422089 0.67220131 0.681623480.10129001 0.19943707 0.29139874 0.37433139 0.44568053 0.50326182 0.54532952 0.57063015 0.578439830.08264056 0.16270211 0.23768966 0.30527334 0.36336372 0.41017869 0.44429984 0.46471615 0.470853890.06336208 0.12472888 0.18217162 0.23389198 0.27828148 0.31397386 0.33988878 0.35526538 0.359684470.04360137 0.0858064 0.12526714 0.16073056 0.19108136 0.21537949 0.23289096 0.24311083 0.245777640.02350833 0.04623087 0.0674093 0.08634588 0.10242699 0.11514595 0.1241207 0.12910605 0.130000290.00323737 0.0063035 0.00903844 0.01130406 0.01299309 0.01403609 0.0144058 0.0141187 0.0132335675°70°65°60°55°50°45°40°35°30°25°20°15°10° 5° 0°5° 10° 15° 20° 25° 30° 35° 40° 45°LATq(nm)
