| 摘 要： | 针对助推-滑翔式再入导弹,提出了一种基于空气动力模型的扩展卡尔曼跟踪算法.首先推导了弹体坐标系和东北天坐标系之间的转换关系,接着描述了两种坐标系下再入目标的空气动力模型,然后建立了目标的运动状态方程和量测方程,给出了扩展卡尔曼滤波过程,最后仿真分析了一条助推-滑翔弹道,并结合该弹道进行了跟踪试验.蒙特卡洛仿真结果表明,所述方法比基于未知输入模型的方法跟踪效果更好,且能有效估计目标的空气动力学系数.

| Abstract: | A tracking method using extended Kalman filter based on aerodynamic model for the boost-glide reentry missile is proposed.Firstly,the transformation between the body-frame coordinate and East-North-Up coordinate is derived.Secondly,the aerodynamic models for the reentry target in the two coordinates are described.Thirdly,the dynamic state equation and measurement equation for the target are presented,and the extended Kalman filter processing is introduced.Finally,a boost-glide trajectory is simulated and an... |
