1.11 Presentation Modes This radar has the following presentation modes: Head-up, Head-up/TB, Course-up, North-up, and True Motion. 1.11.1 Selecting presentation mode Press the [MODE] key on the panel at the right side of the display unit. Each time the [MODE] key is pressed, the presentation mode and mode indication at the upper-left corner of the screen change cyclically. Note: When a failure occurs in the gyrocompass, the radar will automatically be switched to unstabilized presentation mode.
Presentation mode, representative display North marker 350 Heading Marker Heading Line 000 010 340 020 330 030 320 040 310 050 300 Description Head-up mode A display without azimuth stabilization in which the line connecting the center with the top of the display indicates own ship’s heading. 060 290 070 280 080 + 270 090 260 The target pips are painted at their measured distances and in their directions relative to own ship’s heading.
Presentation mode, representative display Description North North-up mode In the north-up mode, target pips are painted at their measured distances and in their true (compass) directions from own ship, north bearing maintained up of the screen. The heading line changes its direction according to the ship’s heading. If the gyrocompass fails, the presentation mode changes to head-up and the north marker disappears. Also, the HDG readout shows xxx.x°.
1.12 Selecting the Range Scale The display range scale is changed by pressing the [+] and [-] keys. The selected range scale and range ring interval are shown at the upper left corner on the screen. When a target of interest comes closer, reduce the range scale so that it appears in 50-90% of the display radius. The range scales are 0.125-0.25-0.5-0.75-1.5-3-6-12-24-48-96 nm. Press the [RANGE] key to select range. The range, range ring interval and pulselength appear at the top left corner of the display.
1.14 Adjusting the Sensitivity The GAIN control adjusts the sensitivity of the receiver. It works in precisely the same manner as the volume control of a broadcast receiver, amplifying the signals received. 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.
1.16 Suppressing Precipitation Clutter The vertical beamwidth of the scanner 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. Figure at right shows the appearance of rain clutter on the display. 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).
1.18 Measuring the Range Use the fixed range rings to obtain a rough estimate of the range to a target. They are the concentric solid circles about own ship, or the sweep origin. The number of rings is automatically determined by the selected range scale and their interval is displayed at the upper-left position of the screen. 1.18.1 Measuring range by the variable range marker (VRM) Use the Variable Range Markers (VRMs) for more accurate measurement of the range to a target. There are two VRMs, No.
1.19 Measuring Bearing Use the Electronic Bearing Lines (EBLs) to find bearing of a target. There are two EBLs, No.1 and No.2, which are toggled by successive presses of the [EBL ON] key. Each EBL is a straight dashed line extending out from the own ship position up to the circumference of the radar picture. The fine dashed line is the No.1 EBL and the coarse dashed one is the No.2 EBL. 1. Press the [EBL ON] key to display either of the EBLs.
If relative motion is selected, it is also possible to read CPA (Closest Point of Approach) by using a VRM as shown below (Figure (a)). If the EBL passes through the sweep origin (own ship) as illustrated (Figure (b)), the target ship is on a collision course. 5. To return the EBL origin to the own ship position, press the [EBL OFFSET] key again.
1.21 Measuring Range and Bearing Between Two Targets 1. Press the [EBL OFFSET] key, and place the origin of the No.1 EBL on a target of interest (target 1 in the illustrated example) by operating the trackball. Note: Only No. 1 EBL can be offset. 2. Turn the EBL rotary control until the EBL passes through another target of interest (target 2). 3. Turn the VRM rotary control until the range marker on the No. 1 EBL aligns with target 2. The NO.
1.22 Setting a Target Alarm Zone CAUTION The target alarm feature should never be relied upon as the sole means for detecting the risk of potential collision. The operator of a ship is not relieved of the responsibility to keep lookout for avoiding collisions, whether or not the radar is in use. 1.22.1 Introduction There are two independent Target Alarm Zones. NO. 1 zone has a default coverage of 3.5-4 nm and is adjustable within 3.0 to 6.0 nm. NO. 2 zone may be adjusted anywhere when the NO.
Note: To create a target alarm zone having a 360-degree coverage around own ship, set point B in almost the same direction (approx. ±3°) as point A and press the [TGT ALARM] key. Two alarm zones can be set as described above. To change the active alarm zones, do steps 1 through 4 in the above procedure. (When both alarms are prepared the active alarm indication is circumscribed.) 1.22.2 Acknowledging alarm A target entering the ALARM zone produces both visual (flashing) and audible (beeping) alarms.
+ + CURSOR CURSOR (a) Select location with cursor (b) Press SHIFT key to offcenter Note: The display is automatically reset to 75% of the range in use whenever the cursor is placed at an edge of the effective display area. Note also that the heading marker (small circle on the bearing scale) leaves the heading line on off-centered display, always indicating the correct direction of the own ship heading. 1.24 Echo Averaging The echo average feature effectively suppresses sea clutter.
(a) Echo average OFF (b) Echo average ON 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 suppressing random echoes such as sea clutter. True echo average is not however effective for picking up small targets running at high speeds over the ground. Echo average is inoperable when a compass signal is not available.
1.25 Electronic Plotting Aid (EPA) 10 targets can be plotted electronically to assess their motion trend. Five past positions can be displayed for each target. Working range of EPA is 0-48 nm irrespective of range scale. Note that EPA is disabled when the ATA (ARP-17) is accommodated. 330 340 350 000 010 020 030 320 040 310 1 050 300 TAZ 290 060 3 1 070 280 080 2 270 090 260 100 250 110 240 120 230 130 220 140 210 200 MAN 00:01 3 TRUE VECT 3Min WT RNG 4.7NM BRG 41.
Note: If a target once plotted is not plotted again within 10 minutes, the warning “UPDATE PLOT” and plot number will appear on the lower right margin of the screen and the plot symbol of the target flashes. Plotting of a target will be ceased if the time between consecutive plots exceeds 10 minutes. If you want to continue plotting this target, reacquire it within 5 minutes. Otherwise, the target will be regarded as a “lost target” and its plot symbol and target data will be erased.
1.25.5 Terminating target plotting With EPA you can plot up to 10 targets. You may wish to terminate plotting of less important targets to newly plot other threatening targets. With Trackball: Place the cursor (+) on a target which you do not want to be tracked any longer by operating the trackball and press the [CANCEL/CLEAR] key.

1.36 Echo Stretch, Contrast, Enhanced Video On long ranges target echoes tend to shrink in the bearing direction, making them difficult to see. On short and medium ranges such as 1.5, 3 and 6 nm scales, the same size targets get smaller on screen as they approach the own ship. These are due to the inherent property of the radiation pattern of the antenna. To enhance target video, use the echo stretch function.

2 OPERATION OF AUTOMATIC TRACKING AID (ATA) ARP-17 2.1 Introduction The FR-1500 MARK-3 series radar can accommodate an optional ATA (Automatic Tracking Aid) module complying with IMO MSC.64(67) Annex 4 and IEC 60872-2. With the optional ATA circuit board (ARP -17) fitted in the display unit, the radar will automatically acquire 10 targets coming into the acquisition area. Once a target is acquired automatically or manually it is automatically tracked within 0.
2.2 Criteria of Tracking A target measuring 800 m or more in the radial or circumferential direction is regarded as a landmass and not acquired or tracked. Echoes smaller than 800 m are regarded as targets to be tracked. The FURUNO ARPA ATA video processor detects targets in the midst of noise and discriminates radar echoes on the basis of their size.
Continued tracking and subsequent calculation develop the relative course and speed of the target just as a man would do when plotting the relative course and speed of the target on the scope with a grease pencil. 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.
2.3 Activating, Deactivating the ATA The ATA is activated/deactivated through the menu. Acquired targets are tracked internally when the ATA is deactivated. 1. Adjust the A/C RAIN, A/C SEA and GAIN controls for proper radar picture. 2. Press [MENU], [7] to show the PLOT MENU 1 1. PLOT MENU 1 MARK DISP OFF ON 2. ERASE 3. VECT REF REL TRUE 4.

2.4 Entering Own Ship’s Speed The ATA requires own ship’s speed and heading data. Of these, the speed data can be entered automatically from a speed log, navaid or manually through the menu. Note: It is customary to use a speed relative to water for collision avoidance and a speed over the ground for navigation purpose. 2.4.1 Automatic speed input 1.

Target-based speed input This mode is used when the ship’s SDME (log) is not operating properly or the vessel has no device which detects ship’s leeward movement (Doppler sonar 2-axis speed log, etc.) and leeward movement is not disregarded. If you select target-based speed, the radar calculates own ship's speed relative to fixed reference targets.
The plot symbol changes its shape according to the status as below. 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 plot symbol changes to a solid mark. If acquisition fails, the target symbol blinks and disappears shortly.
2.5.3 Changing plot symbol mark The plot symbol for a target may be changed after acquiring the target. This feature is available on the R-type radar. 1. Place the cursor on the plot symbol mark you wish to change. 2. Press the [ENTER/SELECT] key successively while pressing and holding down the [HL OFF] control to select plot symbol mark desired.
2.7 Vectors True or Relative Target vectors are displayed in relative or true mode. Own ship does not have a vector in relative mode. You may select true or relative vector with VECT REF on the PLOT MENU 1. 2.7.1 Vector time From the PLOT MENU 1, VECT TIME (or the length of vectors) can be set to 30 seconds, 1, 3, 6, 15 or 30 minutes and the selected vector time is indicated on the screen. The vector tip shows an estimated position of the target after the selected vector time elapses.
2.9 Past Position Display The ATA displays equally time-spaced dots (maximum 10 dots at intervals of 30 seconds, 1, 2, 3 or 6 minutes) marking the past positions of any targets being tracked. 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 in TM mode. In True Motion, the past position display is produced relative to North (True Trails). In Relative Motion, it is relative to North or Heading as selected.
2.11 2.11.1 Alarms CPA/TCPA alarm Visual and audible alarms are generated when the predicted CPA and TCPA of any target become less than their preset limits. The ATA continuously monitors the predicted range at the Closest Point of Approach (CPA) and predicted time to CPA (TCPA) of each tracked target to own ship. When the predicted CPA of any target becomes smaller than a preset CPA alarm range and its predicted TCPA less than a preset TCPA alarm limit, the ATA releases an audible alarm.
2.11.3 Guard zone alarm When a target comes in a guard zone, the audible alarm comes on with the visual indication GUARD ZONE. The intruding target is denoted by an inverted triangle mark. If the target leaves the zone, it changes to a normal tracking symbol (O). You can set the guard zone as follows: 1. Press the [MENU], [7], [7] to display the PLOT menu. 2. Press the [0] key twice. 3. Press the [3] key to select GUARD ZONE. 4. Press the [3] key again to select SET and press the [ENTER/SELECT] key. 5.
2.12 Track Test (Simulation Display) Do this test when the radar is not being used. The simulation display tests the ATA processor for proper operation. The figure below shows the starting picture of the simulation display. Each mark moves as time passes. Check that each target’s data is reasonable. 1. Press [MENU], [7], [7], [0], [0], [4], [4]. 2. Press the [ENTER/SELECT] key to start the test. 3. It takes approximately three minutes for all vectors to be displayed completely on the screen.
2.14 Diagnostic Sequence You can check the ATA Board for proper operation as follows. The self test does not require operator intervention. It runs automatically when the power is placed on at regular intervals or on operator demand. 1. Press [MENU], [0], [0], [0], [0]. 2. Press the [2] key twice to start the diagnosis sequence. The results of the test appear as shown below. FR-1500 M-3 TEST 1. Program No. 03591521** 2. ROM Check OK 3. RAM Check OK 4. Antenna Rotation 24rpm 5.
2.15 Factors Affecting ARPA 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.
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 ARPA or ATA 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.
3 RADAR OBSERVATION 3.1 General 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 scanner position. It is mainly dependent on the pulselength, scanner height, and signal processing such as main bang suppression 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.
Bearing resolution Bearing resolution is the ability of the radar to display as separate pips the echoes received from two targets which are at the same range and close together. It is proportional to the scanner length and reciprocally proportional to the wavelength. The length of the scanner radiator should be chosen 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.
Side lobe echoes Every time the radar pulse is transmitted, some radiation escapes on each side of the beam, called “side lobes.” 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.
3.3 SART (Search and Rescue Transponder) A Search and Rescue Transponder (SART) is generally carried on the SOLAS Convention ships under the GMDSS scheme. It serves as a homing device for the rescue party to reach the survival craft in distress. It is triggered by any X-Band (3 cm) radar within a range of approximately 5 nm (IMO Resolution A.802 (19)). Each radar pulse received causes it to transmit a response which is swept repetitively across the complete radar frequency band.
General remarks on receiving SART Radar range scale When looking for a SART it is preferable to use either the 6 or 12 nautical mile range scale. This is because the total displayed length of the SART response of 12 (or 24) dots may extend approximately 9.5 nautical miles beyond the position of the SART and it is necessary to see a number of response dots to distinguish the SART from other responses.
A/C RAIN control This should be used normally (i.e. to break up areas of rain) when trying to detect a SART response which, being a series of dots, is not affected by the action of the anti-clutter rain circuitry. Note that RACON responses, which are often in the form of a long flash, will be affected by the use of this control. Some sets have automatic/manual anti-clutter rain control facilities in which case the operator is advised to use manual control initially until the SART has been detected.
4 OPERATION OF VIDEO PLOTTER RP-17 (OPTION) (Needed for Radar Mapping) The Video Plotter RP-17 is an optional circuit board which is accommodated in the display unit of the FR-1500 MARK-3 series radars. It permits use of two memory cards: a memory card(RAM) for storing the operator-created radar maps, and the other is a chart card(ROM) storing FURUNO made digital charts. The memory card enables the operator to create radar maps more precisely than the standard supplied radar map card.

5 MAINTENANCE WARNING Do not open the equipment Hazardous voltage which can cause electrical shock exists inside the equipment. Only qualified personnel should work inside the equipment. Turn off the radar power switch before servicing the antenna unit. Post a warning sign near the switch indicating it should not be turned on while the antenna unit is being serviced. Prevent the potential risk of being struck by the rotating antenna and exposure to RF radiation hazard.
6 months to one year 5.2 Terminal strips and plugs in antenna unit Open antenna cover to check terminal strip and plug connections inside. Also check the rubber gasket of antenna covers for deterioration. When closing antenna covers in position, be careful not to catch loose wires between covers and unit. CRT and surrounding components High voltage at CRT and surrounding components attract dust in environment which will cause poor insulation.
