New polyphase pulse compression waveforms and implementation techniques

New polyphase pulse compression waveforms and efficient digital implementation techniques are introduced. The new waveforms make possible previously unobtainable Doppler and/or bandwidth limitation tolerance, and the new implementation techniques allow systems to be implemented with available digital hardware. Doppler tolerance here is taken to mean that the peak response and the peak response to range-time-sidelobe ratio of compressed pulses do not degrade catastrophically with Doppler. Bandwidth limitation tolerance is taken to mean that the peak response to range-time-sidelobe ratio of compressed pulses will not be degraded by the receiver bandwidth limitations necessary to minimize the effect of receiver thermal noise. It is shown that Doppler and bandwidth limitation tolerant digital pulse compressors are feasible for high carrier frequency radars. It is also concluded that such digital compressors have many advantages to offer over analog processors.
