摘要
研究在无人飞行器末制导中,当目标做加速运动时的非线性滤波问题。首先建立了滤波器模型;接着对滤波算法进行了推导;然后利用扩展Kalman滤波方法进行估计。Monte-Carlo仿真表明,该方法可行。
This paper is concerned with the problem of nonlinear filtering in homing guidance when the target moves at the rater of an acceleration. First, a filtering model is built. Then the algorithm of filtering is derived. At last, an estimation is done by extending Kalman filtering method. The Monte - Carlo simulation shows that the method mentioned above is available for use.
