The notion of complementary coding is generally thought to be a waveform design problem. In contrast, here we show that, for arbitrary diverse FM waveforms over the coherent processing interval (CPI), least-squares mismatched filters can be jointly computed to provide complementary sidelobe cancellation on receive when pre-summing of unique waveform subsets is performed after pulse compression (before Doppler processing). The efficacy of this scheme is demonstrated in simulation and with experimental free-space measurements.
