ABSTRACT:
In a track while scan radar which pinpoints a target location by comparing target return voltage summations in the early half of a range gate with those in the late half of the range gate, and with the target return voltage summations in the left half of a multi-pulse azimuth gate with those in the right half of the azimuth gate, noise and clutter are clipped by means of a clipping signal level which is chosen from the lower value of the summation of the early and late target return voltage summations and the summation of the right and left target return voltage summations, thereby using the noise, clutter and target return signal within the target window in one scan to derive the clipping level for a succeeding scan.
