| 摘 要： | 任何天线都有旁瓣,当雷达受到敌方强有源干扰时,进入旁瓣的干扰信号可以淹没主波束接收的目标信号,因而极大地影响了系统性能。为了有效地抑制干扰,在雷达中采用旁瓣对消技术实现空间上的自适应滤波,使来自天线旁瓣的干扰衰减到最小。接收通道的非零带宽和波程差、接收通道频率特性不一致等对旁瓣对消性能有影响。通过仿真对某雷达的旁瓣对消性能进行分析。

| Abstract: | There is the sidelobe with any antenna,the interference signals into the sidelobe will submerge the destination signals received by main-bean when radar receives adversary's strong active jamming and it will affect the system performance greatly.In order to effectively restrain jamming and weaken the jamming from antenna sidelobe be smallest we uses sidelobe cancelling technology to realize spacial adaptive filtering in radar.That of receiving channel's no-zero bandwidth,wave path-difference and receiving c... |
