【摘要】 针对空间直接碰撞拦截目标末制导末端的具体情况，本文采用递推最小二乘估计理论预测相对距离，采用卡尔曼滤波建立侧向运动方程，从而推导了一套实用的末制导末段预测强力开关控制方法并进行了大量的数值仿真。仿真结果表明：末端预测强力开关控制方法是一种消除最终脱靶量十分有效的控制方法。更多还原

【Abstract】 According to the special conditions of the terminal phase in terminal homing for a spaee interceptor,the recourse least square estimation is used to predict the relative range R_r be-tween target and interceptor.And the Kalman filtering is used to set up the lateral dynamics equa-tions so that TESOC(the terminal encounter-point-predicted strong-force on-off control)method based on estimated value theory is derived and a lot of numerical simulations are accomplished with the method.The results and analysis show that TESOC is an efficient method to correct encounter pomt errors.更多还原
