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.

  • Page 25: Adjusting The Sensitivity, Suppressing Sea Clutter

    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.

  • Page 26: Suppressing Precipitation Clutter, Interference Rejector

    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.

  • Page 27: Measuring The 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.

  • Page 28: Measuring Bearing, Collision Assessment By The Offset Ebl

    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.

  • Page 29

    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.

  • Page 30: Measuring Range And Bearing Between Two Targets

    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.

  • Page 31: Setting A Target Alarm Zone

    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.

  • Page 32: Off-centering (shift)

    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.

  • Page 33: Echo Averaging

    CURSOR (a) Select location with cursor 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.

  • Page 34

    Echo average is inoperable when a compass signal is not available. If you wish to use this feature without a compass signal, consult a FURUNO representative. Do not use the Echo Average function under heavy pitching and rolling; loss of target detection can result.

  • Page 35: Electronic Plotting Aid (epa)

    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. 000 010 Target data is shown in the data display area including range, bearing, course, speed, CPA and TCPA of the last-plotted or selected target.

  • Page 36

    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.

    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.

  • Page 64: Criteria Of Tracking

    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. Target whose echo measurements are greater than those of the largest ship in range or tangential extent are usually land and are displayed only as normal radar video.

  • Page 65

    Automatic acquisition areas and suppression lines Performance of auto-acquisition is enhanced by controlling the limit lines (suppression lines) in the former series of FURUNO ARPAs. In the ATA, the automatic acquisition rings are used instead of the limit lines. Auto acquisition rings work as suppression lines when viewed from the opposite direction. They should be placed clear of a landmass or shoreline.

  • Page 66: Activating, Deactivating The Ata

    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 PLOT MENU 1 1.

  • Page 67

    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.

  • Page 68: Acquiring Targets

    2.4.2 Manual speed input Select MAN at step 2 in preceeding procedure, press the [3] key twice, and enter a speed with numeral keypads. 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.

  • Page 69

    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.

  • Page 70: Terminating Tracking Of Targets

    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.

  • Page 71: Vectors True Or Relative, Displaying Target Data

    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.

  • Page 72: Past Position Display, Set And Drift

    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.

  • Page 73

    2.11 Alarms 2.11.1 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.

  • Page 74

    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.

  • Page 77: Factors Affecting Arpa Functions

    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.

  • Page 78

    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.

  • Page 79: General

    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 A. 477 (XII) and IEC 936 require the minimum range to be less than 50 m. All FURUNO radars satisfy this requirement. Maximum range...

  • Page 80: False Echoes

    This is determined by pulselength only. Practically, a 0.08 microsecond pulse offers the discrimination better than 35 m as do so with all FURUNO radars. Test targets for determining the range and bearing resolution are radar reflectors having an...

  • Page 81

    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.

    - Turn off the Interference Rejector. - Turn off the signal processor such as Echo Average. The FR-1500 Mark-3 series radars have a macro feature for easy detection of SART. Press [F1], 0], [ENTER/SELECT]. The following setting is factory provided.

  • Page 83

    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.

  • Page 84: Racon (radar Beacon)

    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.

  • Page 99: Performance Monitor (option)

    A performance monitor is required for a radar installed on certain type of ship as determined by the Administrations. The FURUNO PM-30 (for X-band radars) covers 9410 ± 50 MHz. It works on the transponder principle. It sends response back to the radar antenna upon receiving the pulse from the radar antenna and determines if transmitter or receiver or both are deteriorated in comparison with the state of the precious calibration.
