摘要
单脉冲二次雷达要求天线具有和、差和副瓣抑制三个通道。本文从系统上对三种波束的形成进行了分析和仿真,并采用魔T、Wilkinson功分器和耦合器组成波束形成网络,从工程上进行了精心的设计,结果表明完全满足实际使用的要求。
The monopulse secondary surveillance radar(SSR) antenna needs sum,difference and sidelobe suppression omnidirectional channels. This article provides the analysis and simulation on system level. The beamforming network consists of hybrid tee, Wilkinson divider and coupler, by elaborative designing and engineering consideration. The results indicate that the network is perfect for practical utility.
