12 Radar Systems of Maritime Transport

Fig. 12.3 Radar image in “Course” and “North” modes HO—heading orientation; NO—North
orientation
The advantage of this mode is the orientation of the radar image in accordance with
the situation observed along the course of the ship, and the station ability to operate
in the absence of data from the gyrocompass, and the disadvantage is the lack of
stabilization of the radar image in the direction (yaw).
In the COURSE ST orientation mode, the radar image is stabilized in the direction,
and the OK, as in the COURSE mode, is also always directed upwards, but moves on
the screen in the direction in accordance with the change in the ship’s course within
±15° from the zero of azimuth scale.
