True Bearing Mode [North Up]
The video is displayed so that the zenith of the PPI (0° on range rings) points to the due north. Fixed
targets do not flicker and are easily identified on the chart, and the true bearing of a target can easily
be read out.
Relative Bearing Mode [Head Up]
The video is displayed so that the ship’s heading line points to the zenith of the PPI (0° on range
rings). Since targets are displayed in their directions relative to the ship’s heading line, the operator
can view the video in the same field of view as in operating the ship at sea. This mode is suitable for
watching over other ships.
Course-up Bearing Mode [Course Up]
By setting the course-up mode, own ship's course is fixed so that it is located on the zenith of the
radar display (0° on range rings). In the same way as in the North-up mode, fixed targets do not
flicker, and are stabilized even if the ship is yawing. The bearing of the heading line varies by the
same shift of own ship’s course. To change the course, press the [AZI MODE] key several times
again to select the course-up mode so as to set a new course.
