摘要
为提高弹道导弹的突防能力,对弹道导弹的最优机动突防进行研究。通过对运动模型的简化和分析,确定最优突防方向位于弹道导弹和动能拦截器位置连线的法平面内。基于攻防双方的运动模型,建立多阶段1阶微分运动方程并进行求解,得到弹道导弹最优机动突防时刻的解析表达式。分析突防策略能够承受的模型参数误差限度。为验证所得最优突防时刻和最优突防方向的正确性,进行二维和三维交战模拟仿真。仿真结果表明,采用以最优时刻向相对方向的法平面方向做短时大幅度机动的规避策略可以有效突防,可获得最大脱靶量。
The optimal maneuver penetration of ballistic missiles is studied to improve their penetration capability.Through the simplification and analysis of the motion model,it is determined whether the optimal penetration direction is located in the normal plane connecting the positions of ballistic missile and exoatmospheric kill vehicle.A multi-stage first-order differential motion equation is established based on the motion models of both offensive and defensive parties.The analytical expression of the optimal ballistic missile penetration time is obtained by solving this equation.The error limit of the model parameters that the penetration strategy can support is analyzed.In order to verify the correctness of the obtained optimal penetration time and optimal penetration direction,the two-dimensional and three-dimensional engagement simulations were carried out.The simulated results show that the evading strategy of short-time large pulse maneuver in the direction of the opposite position can be used to effectively penetrate the defense and achieve the maximum miss distance.
