弹道导弹弹道面转移变换规划方法

摘要

The whole traj ectory of the traditional ballistic missile is nearly in the plane made of shooting point,aiming point and the earth’s core,which causes weak ability of maneuvering pene-tration.Aiming at this problem,a strategy of the ballistic plane transfer of ballistic missile was put forward for realizing large range maneuvering on landscape orientation.To realize the strategy,the planning method of the ballistic plane transfer was researched.Based on the ellipse traj ectory theory,the random search algorithm was adopted to optimize the correlated parameters of every ballistic plane.The ballistic traj ectory plane transform required by penetration was realized by using the engine impetus.The simulation calculation shows that the inertial flying time of planning traj ectory becomes shorter,and the planning method of the ballistic plane transfer and penetration are valid.%传统的弹道导弹整个飞行弹道近似在发射点、目标点、地心构成的弹道面内，机动突防能力差，针对此问题，提出了一种弹道导弹弹道面转移的策略，以实现导弹横向大范围机动。为实现这一策略，研究了一种弹道面转移变换的规划方法，基于椭圆弹道理论，利用随机方向法优化各弹道面相关参数，充分运用发动机动力，实现了突防要求的弹道面转移变换。仿真计算表明，惯性段飞行时间大大减少，弹道面转移变换规划方法和突防是有效的。
