ABSTRACT:
A coherence reference signal device, and utilizing radar system therefor, in which a coherent reference signal is provided for phase detection of target echo signals for subsequent application to a canceller or other signal processor. The device recognizes the phase conditions throughout a given transmitted pulse (range bin) and provides this same phase information repetitively for each of n range bins of interest. A tapped sonic delay line of metallic glass material with input and output transducers and a summer circuit provide the coherent reference signal produced to a phase detector which also receives the echo signals, preferably both in the IF frequency domain.
