摘要
介绍了大型船载测控雷达主副瓣自动识别技术的实现方法,通过分析船载大型测控雷达主天线增益高、波束窄,自引导天线增益低、波束宽的特点,提出利用主引天线的接收信号电平差结合电轴不平行度,形成综合判据的技术方案,在伺服主控台(ACU)设备工程应用软件中实现主副瓣的自动识别,通过多次放球和跟踪卫星试验,识别准确率提升25%以上。
This paper introduces a way to identify mainlohe and sidelobe tracking for large shipbome TT ＆ C radar. By taking advantage of the fact that the main antenna has higher gain and narrower beam width than the guiding antenna, we compare the difference of received signals and the e- lectro-axes between main antenna and guiding antenna, then we find a way to realize identification of mainlobe tracking and sidelobe tracking in ACU software, By experiment of tracking ball and satellite, identify accuracy rate is 25% higher than that of traditional methods.
