大型相控阵外监测系统

Outer Surveillance System for Large Phased Array

讨论了大型相控阵外监测原理，解剖分析了系统性能及系统的构建原则，在给出一误差传递模型基础上，讨论了利用外监测方法修正相控阵通道幅相误差所能达到的精度，文末给出了实例分析结果。

The outer surveillance principle of the large phased array is discussed here. Its performances and construction rules are analyzed also. Based on the error transfer model, this paper shows the achievable precision through modifying the amplitude and phase errors of the phased array channels by use of the outer surveillance method. An example is presented at last.
