COMPENSATION METHOD FOR RADAR VIDEO DISPLAY BASED ON TRUE NORTH REFERENCE IN THE SURVEILLANCE RADAR SYSTEM

摘要

PURPOSE: A method for compensating a radar video display based on a true north reference in the surveillance radar system is provided to display all radar videos regardless of the real time change of heading. CONSTITUTION: Whether the veering of a fleet is in a clockwise direction or in a counterclockwise direction is confirmed based on the heading information of a gyro. The interval of an azimuth change pulse is calculated to compensate for the variation amount of heading. The azimuth change pulse is generated according to the calculated interval of the azimuth change pulse.
