Space-time adaptive mismatch processing

Conventional signal processing for GMTI radar (pulse-compression and STAP clutter-cancellation applied sequentially) results in significant losses when pulse-to-pulse waveform diversity is used, because of range-sidelobe modulation. This report describes STAMMP, a method for joint pulse-compression, beamforming, and Doppler processing that mitigates range-sidelobe modulation. The method is partially-adaptive and uses a small number of adaptive degrees of freedom to ensure the filters are robust to radar pointing and calibration errors. SINR is evaluated in a GMTI radar simulation and STAMMP is shown to outperform conventional factored processing approaches.
