摘　　要：通过线性调频信号,研究脉冲多普勒雷达回波信号处理中的脉冲压缩技术,并针对其效果进行仿真分析得出一些有意义的结论。在介绍匹配滤波工作原理的基础上,结合工程实际,给出了实际目标回波脉压的仿真方法及所能达到的性能指标。讨论了影响雷达距离分辨率的因素并进行计算机仿真,为系统实现提供依据。According to LFM, the theory of signal processing of pulse compression radar echo is studied. It＇ s effect is simulated and analyzed. Based on the introduction of match filtering, a method of simulation focusing on the actual echo under pulse compression and the results are given combining with the pmjet practice. Finally, the factors which affect discriminability of distance are discussed and the results are verified by computer simulation in order to provide feasible references to practice.
