  • Page 28: Suppressing Rain Clutter

    A common mistake is too over-adjust the A/C SEA control so that the surface clutter is com- pletely removed. By rotating the control fully clockwise, you will see how dangerous this can be; a dark zone will be created near the center of the screen, causing a loss of close-in targets.

  • Page 29: Measuring Bearing

    Measuring range by VRM 1) Press the VRM ON key to enable a VRM. Each pressing of the key enables the No.1 VRM or No.2 VRM alternately. The active marker’s readout is circumscribed.

    1.16 Collision Assessment by the Offset EBL The origin of the No.1 EBL can be placed any- where with the trackball to assess the risk of col- lision, as well as to measure the range and bearing between two targets. 1) Press the EBL ON key to turn on (or activate) the No.1 EBL.

  • Page 31: Index Lines

    1.18 Index Lines The index lines are useful for maintaining a con- stant distance between own ship and a coastline or partner ship. They can be turned on/off by the INDEX LINE key. Each pressing of the key turns on the index lines (linked with No.2 EBL and No.2 VRM), anchors the index lines, or turns off the index lines.

  • Page 38: Setting A Guard Alarm Zone

    1.28 Setting a Guard Alarm Zone The guard allows the operator to set the desired range and bearing for a guard zone. When ships, islands, landmasses, etc. violate the guard zone an aural alarm sounds and the offending target blinks to call the operator’s attention. Two areas can be set, zone 1 (short dashed line) and zone 2 (long dashed line), and one may be active.

  • Page 40: Suppressing Second-Trace Echoes

    The echo average feature is inoperable when a heading signal is not available. If you wish to use this feature without a heading signal, system ini- tialization is required. (Consult a FURUNO rep- resentative or dealer.) Note: Echo averaging also requires ship’s speed information from a log or manual entry.

  • Page 41: Echo Stretch

    1.32 Echo Stretch 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 range scales, the same sized targets get smaller on screen as they approach own ship. These are due to the inherent property of the ra- diation pattern produced by the antenna.

  • Page 45: Chapter 2 Radar Observation

    Chapter 2 RADAR OBSERVATION 2.1 Radar Picture, Target Properties and Radar Pulse Strength of reflection The strength of the reflected echo depends not only on the height and size of the target but also its shape, material and the angle at which the radio pulse strikes it.

  • Page 46: Bearing Resolution

    2.3 Bearing Resolution Bearing resolution is a measure of the capability of a radar to display as separate targets the echoes re- ceived from two targets which are at the same range and are close together. The principal factor which affects bearing reso- lution is horizontal beamwidth.
