摘　　要：在相位编码脉冲压缩技术中,各种码都存在着多普勒失配问题。本文在分析二相码信号产生多普勒失配原因的基础上,提出了一种最优码的构造码及处理方法,并分析了其性能。该方法不仅降低了二相码对多普勒频移的敏感性,而且与传统二相码信号的直接匹配滤波或相关处理方法相比,具有较大的多普勒容限带宽。经计算机模拟,该方法的有效性得以证实。There lies Doppler mismatch in every code of phase-coded pulse compression tech- niques.Based on the analysis of the causes for Doppler mismatch of binary phase-coded waveforms,a compo- nent code and its processing method is proposed and its performance is analyzed.This method attenuates the sidelobe sensitivity to Doppler mismatch and has larger permissive bandwidth of Doppler mismatch than the customary method by direct match filtering and correlating.Efficiency of the method is proved by computer simulation.
