There lies Doppler mlsmatch in every code of phase-coded pulse compresslOn techmques. Based on the analysis of the causes of Doppler mlsmatch of phase-coded waveforms , a new processmg method is proposed. This method attenuates the sidelobe sensitivity to Doppler mlSmatch and has larger perimissive bandwidth of Doppler mlsmatch than the customary method by direct match filtermg and correlating.
