攻击活动目标的一种最优弹道估计

 为分析活动目标的随机飞行状态和减小导弹的脱靶量,提出了数学模拟打靶的一种新方法。其中包括卡尔曼滤波理论结合最大似然法的应用,以及建立相对运动的离散化模型和灵敏度矩阵。为改善飞行状态的估计精度,论述了确立飞行弹道修正协方差矩阵的概念。除此之外,还讨论了导引敏感器静态误差影响脱靶量的估计问题。

AN OPTIMAL TRAJECTORY ESTIMATE OF ATTACKING MOVING TARGET

A new approach in mathematical analog shoot (MAS) is presented for anlyzing random flight states of the moving targets and guidance miss distances of the missiles. It involves the application of Kalman filter theory combined with maximum likelihood mehtod and the analysis of random factor in flight process such as the deviations of aerodynamic, structural and control parameters of the missiles and any maneuver of the targets. In discussing different error property, the paper describes the method of correct covariances for flight dynamics in order to improve estimation accuracy of flight states In addition, estimation method about static errors of guidance senso; which have influence on the guidance miss distances is also presented in this paper.
