| 摘 要： | 单脉冲雷达发射和接收频率一致,这不可避免地带来了各种反射干扰.航天测控雷达具备针对周围近地反射回波干扰的避盲功能,但对常见的云层回波干扰却没有采取措施,造成雷达在多云或雨天执行任务时,容易受云层(包括云和降水粒子)回波干扰影响.该文对单脉冲雷达云层回波的成因、特征及其影响进行分析,提出航天测控任务中,单脉冲雷达如何躲避云层回波干扰影响的具体方法.

| Abstract: | Receiver and transmitter of monopulse radar are worked at the same frequency.This character of monopulse radar,receiving frequency is the same with emissive frequency,bings various echo interferences to radar.In planning of monoplulse radar,the reflected electromagnetic wave,which is come from the immediate vicinity of radar,has been considered.But the radar lacks a method to avoiding interference of the familiar cloud echo.In a cloudy or rainy day,the cloud echo would interfere with the radar's working.Thi... |
