Doppler tolerant time separated Golay waveforms

Abstract

A radar transmission and processing scheme is developed which yields range profile estimates with target mainlobes which are as narrow as possible and sidelobe levels which are low. Specifically, Golay waveforms are implemented via time separated waveform transmission and the Re-Iterative Super Resolution (RISR) algorithm [9]. Doppler tolerance is achieved by using Golay quads in addition to Doppler bin specific fast-time Doppler compensation. The four waveforms of the Golay quad are transmitted in four sequential bursts at a fixed pulse repetition interval. The RISR algorithm is used to separate the received signal into discrete Doppler bins. The separated signal components are then compensated appropriately so that the Golay complementarity property can be exploited. The time separated Golay transmission and processing scheme is illustrated with simple simulation examples.
