引言旁瓣匿影,即从雷达回波中消除低占空比的旁瓣干扰,一直是人们感兴趣的技术。此技术是在雷达系统中增加一个辅助天线和接收通道,两通道的输出(即主、副通道)进行联合处理。近年来,它也成为防止相干机载雷达接收机中由于强而离散的旁瓣杂波所引起的虚警的有利技术。我们将对具有三种性质不同的判定逻辑的旁瓣匿影(或称保护通道)系统的性能进行比较。
INTRODUCTION Side lobe anomalies, the elimination of side-lobe interference at low duty cycles from radar echoes, have been the technology of interest. This technique adds an auxiliary antenna and receive channel to the radar system, and the two channels of output (ie, primary and secondary channels) are jointly processed. In recent years, it has also become an advantageous technique to prevent false alarms caused by strong and discrete sidelobe clutter in coherent airborne radar receivers. We will compare the performance of a sidelobe anonymity (or guard channel) system with three discriminating logic of a different nature.
