| 摘 要： | 雷达信号处理的根本目的是从杂波中提取运动目标 ,本文从杂波有效抑制的角度对X波段测高雷达进行PRF设计。对设计结果的分析表明 ,X波段雷达采用中脉冲重复频率PD体制 ,信杂比改善因子增大 ,有利于云雨杂波背景下目标信号的检测 ;同时 ,虽然增加了距离解模糊电路 ,但可以省去脉冲压缩电路 ,综合效能明显提高

| Abstract: | This key aim of radar sigal processing is to extract moving target from clutter.From the viewpoint of clutter depression,this paper describes the PRF design of X-band height-finding radar.The analysis of the design result shows that by using the medium-PRF PD system in X-band radar,the improvement factor of S/C will be increased and it is benefical to the target signal detection in cloud or rain clutter.At the same time,although the distance de-ambiguity circuit should be added in this scheme, the pulse compression circuit can be left out,so the comprehensive performance will be increased significantly. |
