| 摘 要： | 本文研究将改进的推广Ｋａｌｍａｎ滤波器应用于导弹被动制导问题。为了提高系统的可观性，我们采用一种双重指标来设计最优导引律。仿真结果表明，如何系统状态的均值较高，波动较小，那么ＭＥＫＦ的估计精度明显优于推广Ｋａｌｍａｎ滤波器。

| Abstract: | A modified extended Kalman filter(MEKF)is proposed and applied to passive missile guidance We adopt a dual control method to design guidance law for enhancing the observability content of the control system Simulation results indicate that if the expectation of the system state is relatively large and the wave of the state is relatively minor,the performance of the MEKF is much better than that of the extended Kalman filter(EKF). |
