摘要
提出了一种基于多模多极化天线的单脉冲二维跟踪方法,分析了多模多极化天线波束形成和角度跟踪信息提取的原理。应用该方法可以实现高侦察灵敏度和跟踪精度,适合对远距离星载雷达副瓣信号的快速截获与精确跟踪,具有较大的应用价值。
2D monopulse tracking method based on multi-mode-multi-polarized antenna array is given firstly.Then the beam forming principle based on multi-mode-multi-polarized antenna array and the extraction algorithm of angle tracking information is analyzed.Electronic reconnaissance system sensitivity could be improved much better with this method,the angle tracking accuracy is also.So the method is proper for tracking space-borne radar through side-lobe signal interception.
