The application of a surface acoustic wave power cepstrum analyser to the problem of automatic discrimination of pulsed and CW interference signals is discussed. The SAW processor can analyse signals of duration up to 25 μs and bandwidth 6 MHz and with suitable frame-to-frame tagging of the processor output it is possible to discriminate responses due to CW interference yielding an unambiguous record of the input pulse.
