| 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。

| Abstract: | 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. |
