Abstract

An acousto-optic processor capable of analyzing signals consisting of a high frequency carrier modulated by an envelope signal is described. Space-integrating spectral analysis is used to channelize signals by carrier frequency. Time-integrating spectral analysis is used to characterize the envelope signal that modulates each carrier frequency. The output is a two- dimensional display with carrier frequency along one axis and envelope frequency along the orthogonal axis. Several advantages of the processor are explained and proof-of-concept experimental results are presented. One possible application of the processor is to the automatic separation and determination of the carrier frequencies and pulse repetition frequencies of multiple received radar signals.
