对机动目标的滤波和预测研究(上)

On the Filtering and Predicating Maneuvering Target

因反超音速导弹和末端机动导弹的需求,必需解决对机动目标的跟踪滤波和预测问题。根据对机动目标运动特性和噪声特性的分析,指出不能用处理平稳随机过程的最佳滤波方法来处理非平稳随机过程的滤波问题。利用自动控制理论、自适应控制方法和误差相消技术,构建了对付机动目标的滤波器,并给合常用的几条航路和一条完整的末端机动导弹航路,进行了模拟仿真计算,获得了较好的结果。最后,还给出了能补偿系统偏差的预测方法。

Because of the requirements of ant-supersonic and ant-terminal maneuveZring missile,the problem of filtering and predicating the maneuvering target must be solved.By analyzing the move and noise of the maneuvering target,this paper make a point：the optimum filtering method can be treated the non-maneuvering target in stationary random process,but can not be treated the maneuvering target in non-stationary random process.The filter for maneuvering target is designed by applying the principle of servo system,error compensation and adaptive control method.The results are provided by calculating several common routes and a full target route of ant-warship missile which maneuvering in its end region.This paper also design a predication method that is used compensating the system error.
