摘要
运用Kalman滤波方法对再入飞行器的跟踪问题进行了分析,在动力学噪声已知的情况下,给出了一种弹道系数的自适应估计方法;在动力学噪声未知时,给出了弹道系数和动力学噪声方差的自适应估计方法。仿真算例表明这种方法是合理有效的。
The tracking problems of reentry aerocraft are analyzed by using Kalman filter. On the one hand,an adaptive estimation of trajectory coefficient is given with known model noise,on the other hand,adaptive estimations of trajectory coefficient and noise variance are given with unknown model noise. The simulation shows the method is reasonable and effective.
