摘要
在建立适当信号环境模型及对消模型的基础上 ,深入分析了“爱国者”雷达系统旁瓣对消性能。首次提出了干扰源数与对消阵元数“匹配”的概念 ,并分析了系统在“匹配”工作模式下可能具有的对消能力。仿真结果显示 ,在匹配模式下 ,“爱国者”雷达系统对一个干扰源具有优良的对消性能 ,对两个干扰源也具有较好的对消能力。同时 。
The sidelobe cancellation performance of the Patriot radar system is deeply evaluated . Signal model and cancellation model for the radar system are first discussed, which are the basis for the performance analysis. The matched model of the requirement for the number of jammers and auxiliary antennas are first discussed, and the corresponding cancellation performance is simulated explicitly. Simulation results indicate that the Patriot radar system shares the excellent cancellation performance when only one jammer exists, and the sidelobe cancellation system is also useful when two jammers exist. In the end, some useful conclusions are drawn.
