1. A coherent sidelobe canceler for communications systems providing effective continued operation within environments of large clutter and high pulse interference comprising:

  • A plurality of CSLC loops, each having;

    CSLC correlation filter means responsive inclusively to a CSLC residue output signal and a CSLC INHIBIT signal,CSLC limiter means responsive to an auxiliary input signal and providing a limited output signal to said correlation filter means,CSLC vector modulator means inclusively responsive to said auxiliary input signal and a signal provided as output from said CSLC correlation filter means;

    CSLC summing means responsive to the signal outputs from said vector modulator means and furnishing an output signal;

    CSLC subtractor means responsive to a main input signal and the output signal furnished by said CSLC summing means;

    CSLC sensing circuit means responsive to said CSLC residue and generating said CSLC INHIBIT signals.
