Abstract

The U.S. Army Missile Command is investigating several optical correlator systems for target acquisition, recognition, and tracking. The correlation signal is often less than ideal and surrounded by a very noisy background. A morphological approach to noise rejection in the correlation plane could enhance the performance of these systems. A morphological algorithm, realized via threshold decomposition, has been tested to provide noise rejection in the correlation plane of an optical correlator system. The peak-signal-to-peak-noise ratio has been greatly enhanced, and this algorithm lends itself to implementation as a real-time (video frame rate) processor.
