摘　　要：在相位编码脉冲压缩技术中,各种码都存在着多卜勒失配的问题。本文根据m-序列码的移位相乘性质,提出了一种扩展m-序列编码连续波信号多卜勒频移容限带宽的方法,并分析了该方法的多卜勒失配性能。该方法降低了旁瓣电平对多卜勒频移的敏感性,与传统编码信号的处理方法相比,具有较大的多卜勒容限带宽。经计算机模拟,证实了该方法的有效性。Each of codes has Doppler mismatch in the phase-coded waveforms.Based on the feature of multiplication of m-sequence,this paper proposes a method which expands the permissive Doppler mismatch bandwidth,and analyzes the Dopoler mismatch performance of the method.The method atteuates the sidelobes sensitivity to Doppler mismatch and has longer permissive Doppler bandwidth than the customary method.It's shown thoat the method is effective by computer simulation.
