Title: Fully-coherent multiple frequency radar system

Abstract: A multiple frequency radar system having improved signal-to-clutter performance. A transmitter responsively coupled to a spacing frequency generator transmits a plurality of mutually coherent frequencies uniformally spaced apart in frequency. An associated non-linear receiver includes a phase detector responsive to the spacing frequency generator for coherent processing of receiver signals provided in response to echoes of the transmitted signal.
