1. A multiple-input multiple-output (MIMO) radar system for monitoring motion of a movable target, comprising;

  • at least two spatially offset transmitting antennas, wherein at least two distinguishable waveform signals are simultaneously transmitted;

    a plurality of receiving antennas adapted to receive incoming waveform returns for each of said at least two distinguishable waveform signals;

    a displaced phase center antenna processing unit operatively connected to said receiving antennas and adapted to process said incoming waveform returns for each of said at least two distinguishable waveform signals;

    a synthetic aperture radar (SAR) processing unit operatively connected to said receiving antennas and adapted to produce from said incoming radar signals a plurality of spatially-coincident SAR-processed signals;

    a processing circuit operatively connected to the SAR processing unit and the DPCA processing unit and adapted to generate a plurality of clutter-suppressed signals using the spatially-coincident SAR-processed signals.
