    During this developmental period, which may last for several years, there is no guarantee of the accuracy, integrity, continuity, or availability of the SBAS signal. Furuno will accept no responsibility for the use of the signal for other than the above stated purpose. It is the user’s responsibility to exercise common prudence and navigational judgment while using the SBAS signal.

    2. RADAR OPERATION Reducing Sea Clutter 2.5.1 How the A/C SEA works Echoes from waves can be troublesome, covering the central part of the display with random signals known as “sea clutter”. The higher the waves and the higher the antenna above the water, the further the clutter will extend. Sea clutter may affect radar performance because real targets are sometimes hidden by the echoes of small waves.

Targets are painted at their measured distances and in their directions relative to own ship’s heading. The short line on the bearing scale is the north marker.
  • Page 46 2. RADAR OPERATION North-up In the north-up mode, targets are painted at their measured distances and in their true (compass) directions from own ship. North is maintained at the top of the screen. The heading line changes its direction according to ship’s heading. True motion Fixed radar targets maintain a constant position on the screen, while your own ship moves across the radar image at the correct speed and heading.

  • Page 47: Measuring The Range

    2.10 Measuring the Range You can measure the range to a radar target three ways: by the range rings, by the cursor, and by the VRM (Variable Range Marker). 2.10.1 Measuring range by range rings Count the number of rings between the center of the display and the target. Check the range ring interval and judge the distance of the echo from the inner edge of the nearest ring.

    2. RADAR OPERATION 2.19 Echo Stretch Normally, the reflected echoes from long range targets appear on the display as weaker and smaller blips even though they are compensated by the radar’s internal circuitry. The echo stretch function magnifies these small blips in all ranges.

  • Page 63: Echo Averaging

    2.20 Echo Averaging The echo average feature, which requires a Model 1800/1900 series network radar, effectively suppresses sea clutter. Echoes received from stable targets such as ships appear on the screen at almost the same position during every rotation of the antenna. On the other hand, unstable echoes such as sea clutter appear at random positions.

  • Page 64: Outputting Tll Data

    2. RADAR OPERATION 2.21 Outputting TLL Data Target position data can be output to units of the network and shown on their plotter screen with the TTL mark ( heading data. 1. Operate the trackball to place the cursor on the target whose position you wish to output.

  • Page 65: Guard Alarm

    2.22 Guard Alarm The guard alarm allows the operator to set the desired range and bearing for a guard zone. When ships, islands, landmasses, etc. violate the guard zone, an audio alarm sounds and the offending target blinks to call the operator’s attention.

  • Page 66: When The Alarm Is Violated

    2. RADAR OPERATION The equipment then searches for targets inside the guard zone to determine guard alarm type. If a target is found inside the guard zone, the guard zone type becomes an “Outward guard alarm,” and any target exiting the guard zone will trigger the audio alarm.

  • Page 67: Watchman

    2.23 Watchman 2.23.1 How watchman works The watchman function periodically transmits radar pulses for one minute to check for targets in a guard zone. If a target is found in the zone, watchman is cancelled, the audio alarm sounds and the radar continues transmitting. If no target is found the radar goes into standby for the number of minutes specified on the RADAR DISPLAY SETUP menu.

  • Page 68: Suppressing Second-Trace Echoes

    2. RADAR OPERATION 2.24 Suppressing Second-trace Echoes In certain situations, echoes from very distance targets may appear as false echoes (second-trace echoes) on the screen. This occurs when the return echo is received one transmission cycle later, or after a next radar pulse has been transmitted.

  • Page 75: Setting Vector Attributes (Arp)

    2.26.5 Setting vector attributes (ARP) What is a vector? A vector is a line extending from a tracked target which shows estimated speed and course of the target. The vector tip shows an estimated position of the target after the selected vector time elapses. It can be useful to extend the vector length (time) in order to evaluate the risk of collision with any target.

    2. RADAR OPERATION 2.26.6 Displaying past position (ARP) This ARP can display time-spaced dots (maximum ten dots) marking the past positions of any targets being tracked. You can evaluate a target’s actions by the spacing between dots. Below are examples of dot spacing and target movement. To turn the past position display on or off: 1.

  • Page 80: Interpreting The Radar Display

    2. RADAR OPERATION 2.27 Interpreting the Radar Display 2.27.1 General 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 m from the point representing the antenna position.
  • Page 81 2. RADAR OPERATION 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 the echoes received from two targets, which are at the same range and close together, as separate targets. Bearing resolution is directly proportional to the antenna length, and inversely proportional to the radar's wavelength.

    2. RADAR OPERATION 2.27.2 False echoes Occasionally echo signals appear on the screen at positions where there is no target or disappear even if there are targets. False target situations may be recognized, however, if you understand why they are displayed. Typical false echoes are shown below.
  • Page 83 Virtual image A relatively large target close to your ship may show 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.

    2. RADAR OPERATION 2.27.3 SART (Search and Rescue Transponder) 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.
  • Page 85 2. RADAR OPERATION General procedure for detecting SART response 1. Use the range scale of 6 or 12 nm as the spacing between the SART responses is about 0.6 nm (1125 m) to distinguish the SART. 2. Turn off the automatic clutter suppression (if applicable). 3.

    2. RADAR OPERATION A/C SEA control For optimum range SART detection, this control should be set to the minimum. Care should be exercised as wanted target in sea clutter may be obscured. Note also that in clutter conditions the first few dots of the SART response may not be detectable, irrespective of the setting of the anti-clutter sea control.
