Abstract

PURPOSE:To prevent the tracking of the image under a horizontal plane and the tracking of clutters by controlling an antenna in accordance with the movement information of the target position obtained during normal tracking. CONSTITUTION:When the radar device tracks an image while tracking at a low altitude, an antenna 1 directs downward, and the difference between the smoothing depression and elevation angle signal E* which was under reproduction and calculation by a computer 9 in accordance with the movement of the target till then and the current antenna depression and elevation angle signal E increases. Hence it is compared in a comparator 11' in an input switch 10' and when said difference exceeds the predetermined value, a relay 12' is changed over to feed the differential signal epsilonE=E-E* between the smoothing depression and elevation angle signal and the antenna depression and elevation angle signal to an antenna controlling mechanism 5' so that the tracking is continued on the premise that the target flies at the speed and course before the changing over. Thereby, the antenna 1 is prevented from tracking the image appearing under the horizontal plane.
