Good practical continuous waveform for active bistatic radar

In monostatic continuous wave (CW) radar the dominant waveform is periodic linear frequency modulation, mostly because its stretch processing requires sampling rate much lower than the bandwidth. In a bistatic scene a clean copy of the transmitted signal, required in stretch processing, is not available to the receiver. That opens the competition for other periodic waveforms. The authors study describes and demonstrates, through bistatic field trials, the good performances of bi-phase and tri-phase CW waveforms. Among their advantages are sidelobe-free range response, availability at all prime lengths and ease of synchronisation. Successful bistatic operation is a prerequisite for multistatic systems.
