Radar Pulse Compression Repair

This correspondence presents an adaptive approach for range sidelobe mitigation for use by future radar systems as well as in-service radar systems in which the precompressed received signal may not be readily available or it may not be feasible to replace the current pulse compression system. The approach, denoted as pulse compression repair (PCR), utilizes a previously developed adaptive technique to operate on the match filtered output treating the resulting waveform autocorrelation as if it were the transmitted waveform thus "repairing" the effects of range-sidelobe masking that are induced by matched filtering. Illustrative results are presented comparing PCR with the matched filter and the CLEAN algorithm which demonstrate significant performance advantages for PCR as well as robustness to Doppler mismatch and system errors.
