Kalman filtering can be used for target tracking, both in electronic scan radar systems and in mechnical scan radar systems. In the former systems, it is used to directly initiate beams to move, while in the latter systems, it is used for exact measurement without the problems caused by servo tracking structure. The tracking loop formed by Kalman filtering will have target bias-zero tracked, when working in parallel with the servo-tracking loop. The state estimation of Kalman filtering serves as coordinate output of radar measurement as well as complex control signal for serve systems, so as to realize computer-aided-tracking. The video closing test shows that it" has satisfacfory performance.In order to improve the accuracy and to solve the problems caused by the difference between model designing and actual moving of targets, this paper presents an adaptive method of detecting maneuvering by mean-variance and modifying gain directly. The flying tests of an experimental scan array radar shows that this method has more effective result than those without adaptive constant coefficient tracking systems.

在电扫描或机械扫描雷达中均可利用Kalman滤波方法进行跟踪。Kalman滤波形成的跟踪回路是对目标进行偏零跟踪,它与伺服跟踪回路并联工作。Kalman滤波的状态估计作为雷达测得的座标输出,同时还作为伺服系统复合控制信号,实现计算机辅助跟踪。 为了提高精度和解决模型设计与目标实际运动的差异而引起的问题,文中提出用均值和方差联合检测及直接修改增益矩阵的自适应方法,经实验性相控阵雷达飞行试验表明,这种方法比不用自适应的常系数跟踪系统具有更好的效果。
