介绍了脉冲多普勒天气雷达解速度模糊和消距离模糊的原理，给出了几种常用解模糊方法的具体算法及其仿真结果，并对不同处理方法的性能进行了比较。描述了在某x波段车载脉冲多普勒天气雷达以通用DSP芯片TMS320C6701为核心的信号处理系统中，采用双脉冲重复频率解模糊的具体实现方法，最后给出了解速度模糊和消距离模糊的实际效果图。

This article introduces the pr/nciple of anti-illegibility for doppler weather radar, describing several algorithm and simulation results. The performances of different processing manner is compared particularly. And this paper also provides an application of signal processing system of an x - band vehicle-mounted pulse Doppler weather radar, which adopts the method of DPRF for anti-illegibility based on TMS320C6701 DSP hardware platform. Finally several pictures of radar anti-illegibility results are shown as well.
