ABSTRACT:
An active phase quieting target highlight detector using phase and magnitude detection. In contrast to classical magnitude-only detection schemes, the present invention, by combining phase detection, can discriminate sets of spatially-ordered highlights due to a target, from clutter or multipath echoes, along with nonsmoothed magnitude or envelope detection, that can better discriminate target structure due to reception of echoes from shorter active pulses. False target detection and multipath detection are reduced while detection or target structure is retained by the time domain detection scheme of the invention.
