Abstract
Abstract An antenna is connected to a surveillance sensor feeding a target detector. The target detector provides multiple inputs of target reports, azimuth, range and scan count data to a clutter mapper circuit which in turn feeds a track-while-scan circuit one output of which is fed back to a data input buffer also feeding the clutter mapper circuit. Another output of the track-while-scan circuit provides input to a CRT display.
