ABSTRACT:
A vehicle mounted radar system has an antenna (12) which rotates about a reference axis (19). During angular movement of the antenna with respect to the reference axis, a radar indicated target azimuth (.phi.') is modified to provide a corrected target azimuth (.phi.) which is substantially indicative of the actual or true target azimuth. A tracking system (25) uses a predicted radar indicated target position (P.sub.n+1 (x,y)) for target tracking and correlation. The tracking system uses a smoothed target position (STP(x,y)), indicative of actual target position, for providing a visual display (39) of target track.
