摘要: 研究了阵列雷达中快速目标截获的两个关键问题:角度测量和角度预测.首先,从测角原理、要求的波位排布、鉴别特性和测角性能等几个方面研究了阵列雷达中快速目标截获的两种测角算法:幅度比较类单脉冲和幅度加权平均,提出了这两种算法在工程应用中的引导和非线性校正方法;然后,分析了利用跟踪滤波器的角度预测算法,提出了SDF跟踪滤波器;最后,在某阵列雷达仿真系统中进行了仿真研究.

Abstract: Two key-problems,angle measurement and angle prediction, of the swift target acquisition in array radar are studied. Firstly, from the respect of required beam arrangement, discrimination feature and the performance of angle measurement, the two algorithms named amplitude-comparison monopulse-like algorithm and average weighted with amplitude algorithm, for measuring the target-s angle with array radars are studied. The method for nonlinear adjustment when the average weighted with amplitude algorithm is applied is posed. Then, the algorithms for predicting the target-s angle with tracking filters are analysed. A simple decoupled filter named SDF is presented. At last, these algorithms are tested in a simulation system for array radar.
