摘要：
In multstatic radar it is desirable to transmit waveforms which are completely mutually orthogonal in order to minimise cross-transmitter interference. Perfect orthogonality is impossible to achieve, and in reality adaptive processing is necessary to remove interference, with some mismatch loss in main lobe size. This study proposes a method of composing waveforms from mutually-orthogonal complementary sets. Each transmitter is assigned a set of complementary waveforms to be separated in frequency. Nonlinear processing of matched filter outputs can completely remove cross-transmitter interference and suppress autocorrelation sidelobes without cost. Cross terms introduced by the nonlinear operation are handled via frequency agility and Doppler processing. The principle is demonstrated by simulation.
