| 摘 要： | 介绍了Kalman滤波的基本方程及其产生发散的原因,研究了一种抑制Kalman滤波发散的方法,此方法通过减小老数据的影响,不断更新＂新息＂,达到对状态估计值的修正,并缩小真实值和状态估计值之间的差距,从而抑制Kalman滤波发散并将其应用到雷达跟踪问题上,通过Matlab仿真,说明了此方法有着现实的重要意义。

| Abstract: | This paper introduces the elementary equation of Kalman filter and the reasons of divergence.we research a method of restraing Kalman filter.It can reduce distance between the reality value and the state estimate value and modify the state estimate value by reducing influence of the old data and updating continuously innovation and restrain Kalman filter divergence and appliance of the method to radar tracking by Matlab emulate,shows the significance of the method. |
