摘　　要：在相位编码信号脉冲压缩技术中,存在着多普勒频率敏感性问题,需要对多普勒频率进行补偿。在分析多普勒敏感性原因的基础上,提出了一种基于共轭的发射码字的补偿算法,可以从根本上解决相位编码信号对多普勒频率的敏感性问题,MATLAB仿真证明了该算法的正确性与可行性。In phase-coded signals pulse compression techniques, Doppler frequency compensation is needed because of phase-coded signals＇ Doppler frequency sensitivity. After analysising the causes of Doppler frequency sensitivity, a new compensation method based on conjugated transmission code is proposed. This method can attenuate the Doppler frequency sensitivity ultimately. And its validity and feasibility have been verified by simulation.
