摘要
现代高技术战争条件下 ,电子战任务和电磁环境中威胁信号形式变得更加多样复杂 ,要求电子战支援系统 (ESM)天线传感器能够接收和检测各种不同极化的威胁信号 ,即具有全极化接收能力。本文首先简要的介绍了一种性能优良的天线—双极化曲折天线 (DPSA) ,然后提出了利用单个双极化曲折天线 ,将现有机载雷达告警接收机升级为全极化接收机系统的四种解决方案 ,其中重点介绍了基于极化组合 /分解思想的第四种方案。
In modern high Tech war,the EW mission and threaten are becoming complicated,ESW must be capable of receiving any polarized incoming signals.In this paper,we first briefly introduce a good performance antenna--dual polarized sinuous antenna,and then put forward four design solutions for upgrade the existing single polarized RWR to omnipolarized RWR using single DPSA.In this paper,the fourth viz.the best design solution based on the idea of polarization combination/decomposition is discussed in detail.
