Radar pulse compression is widely used to achieve high range resolution without the attendant high-peak power that would otherwise be required through the use of an unmodulated short pulse. The wide variety of different waveform structures also provides a means to distinguish the echoes from different radars that may coincide in space, frequency and time. Furthermore, the development of new waveform-diverse emission schemes relies on the ability to adequately separate the various emission components within the receiver. Viewing these scenarios as belonging to the general framework of signal separation problems, in which the different signals mutually interfere, this chapter describes an adaptive receive scheme through which these different signal components can be extricated so as to realize the required radar sensitivity. Specific applications addressed include multistatic radar, imaging for high Doppler scenarios and stepped-frequency transmission.
