摘　　要：采用简化的目标多点散射模型生成引信接收的多普勒信号 ,叙述了几种现代防空导弹多普勒体制近炸引信的信号数字处理方法 ,并进行数字仿真 ,按仿真结果给出了目标多普勒信号波形、频谱和主频随时间的变化 ,比较了几种多普勒主频率的提取方法的优缺点及其适用范围 。Several method of digital signal processing for anti air missile's DP proximity fuze by mean's of simplified multipoint scattering model which generates fuze receiving DP signal is discassed and the digital simulation are carried out and the result provides the change in DP waveform, spectrum main frequency in time. In the pape the comparison of the adavatages of main DP frequency selections and their application are also presented, meanwhile some sugestion are put out about signal processing of fuze optimal start zone.
