摘要
本文探讨了利用雷达主天线的变极化特性和辅助天线相结合来识别有源假目标欺骗干扰的可行性。首先建立了主辅天线对雷达目标和有源假目标干扰的接收信号模型。在此基础上,根据有源真假目标回波特性直观的差异提出了识别判决检验量,设计了有源真假目标的识别算法。最后,结合有源假目标干扰的极化特性,具体分析、评估了利用辅天线进行有源假目标欺骗干扰识别的性能。
The feasibility of discriminating active-decoys and radar targets by utilizing polarization characteristics of radar main antenna and sidelobe-canceller antenna is discussed in this paper. Firstly,the received signal models of main antenna and sidelobe-canceller antenna are presented. Then, the characteristics of active-decoys and radar target are analyzed, the identification test and identification algorithm of active-decoys and radar targets are also presented. Finally, the identification performance is analyzed and evaluated.
