摘　　要：传统脉冲雷达中作用距离和距离分辨力之间存在矛盾,这是脉冲压缩技术的由来,文章以线性调频信号为例讲述了脉冲压缩的基本原理和数字脉冲压缩的两种实现方式,以及匹配滤波器的实现,结合MATLAB仿真结果直观地说明了脉冲压缩的特点,并阐述了副瓣抑制的两种实现方式,给出了加权前后及不同加权方式的仿真效果对比。This paper takes the contradiction between operating range and range resolution of traditional pulse radar for example and introduces the origination of pulse compression signal.It takes linear frequency modulation signal as an example.The paper analyses the principle of pulse compression and two methods of digital pulse compression,and the accomplishment of matching filter.Combining the simulation result of digital pulse compression algorithm by using MATLAB,this paper discusses the character of pulse compression.In the end,this paper describes two implementation methods of range side lobes suppression.The simulation results show the difference of weighted before and after,and the difference between different weighted ways.
