Abstract

This paper describes an optical correlator for use in sonar ranging. The sonar system must process low probability of intercept signals while consuming minimum power. An optical correlator is favored because of the high efficiency of optical components and the low duty cycle, afforded by the high speed of the optical processing. The correlator is of the time integrating class because this approach permits the processing of extremely large time- bandwidth-product signals ($OM106).
