  • Page 42: Presentation Modes

    1. RADAR OPERATION 1.12 Presentation Modes This radar has the following presentation modes: Relative Motion (RM) Head-up: Unstabilized Head-up TB: Head-up with compass-stabilized bearing scale (True Bearing) where the bearing scale rotates with the compass reading. Course-up: Compass-stabilized relative to ship’s orientation at the time of selecting course-up.

  • Page 43: Description Of Presentation Modes

    1. RADAR OPERATION 1.12.2 Description of presentation modes Head-up mode The head-up mode is a display in which the line connecting own ship and the top of the display indicates own ship’s heading. The target pips are painted at their measured distances and in their directions relative to own ship’s heading.
  • Page 44 1. RADAR OPERATION Head-up TB (True Bearing) mode Radar echoes are shown in the same way as in the head-up mode. The difference from normal head-up presentation lies in the orientation of the bearing scale. The bearing scale is heading sensor stabilized. That is, it rotates in accordance with the heading sensor signal, enabling you to know own ship’s heading at a glance.
  • Page 45 1. RADAR OPERATION True motion mode Own ship and other moving objects move in accordance with their true courses and speed. In ground stabilized TM, all fixed targets, such as landmasses, appear as stationary echoes. In the sea stabilized TM without set and drift inputs, the landmass can move on the screen.

  • Page 46: Entering Own Ship's Speed

    The ARP and azimuth stabilized presentation modes require own ship speed input and compass signal. The speed can be entered from a log (STW) or GPS (SOG) or manually on the menu. Note that FURUNO GPS Navigator GP-90 provides COG and SOG.

  • Page 47: Manual Speed Input

    1. RADAR OPERATION 1.13.2 Manual speed input If the speed log is not working, enter speed manually as below. In this case the speed data type is shown as MANUAL and is speed thru water (STW). Manual speed input is not available when the AIS feature is active. 1.

  • Page 54: Suppressing Rain Clutter

    1. RADAR OPERATION 1.18 Suppressing Rain Clutter Use the AUTO RAIN and A/C RAIN to suppress rain clutter. AUTO RAIN suppresses rain clutter in the picture and A/C RAIN suppresses clutter picked up by the antenna. 1.18.1 Turning AUTO RAIN on or off 1.

  • Page 55: Adjusting A/C Rain

    1. RADAR OPERATION 1.18.2 Adjusting A/C RAIN The vertical beam width of the antenna 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. 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).

  • Page 56: Interference Rejector

    1. RADAR OPERATION 1.19 Interference Rejector Mutual radar interference may occur in the vicinity of another shipborne radar operating in the same frequency band.
