摘　　要：简要回顾PD雷达信号处理方法,结合某PD雷达信号处理机研制,阐述该信号处理机的软硬件实现方法。其硬件平台以8片TS201芯片为核心,通过链路口实现相互间点对点的通信。实现了PD雷达距离门选通工作模式下各距离门的多普勒滤波以及恒虚警处理等。Signal processing methods in pulse Doppler （PD） radar is reviewed in brief. Hardware and software implementation of a radar signal processor in a PD radar is described. Its hardware platform is based on eight pieces of chips TS201, and point-to-point communications is realized via link ports. In operating mode of range gating, Doppler filtering and constant false alarm rate （CFAR） processing to each range gate are achieved.
