摘要
提出了一个基于脉冲式变轨的弹道导弹突防的方法,利用此方法设计的弹道是由几条不同的椭圆弧段组成,这种弹道不同于经典弹道和其它弹头机动弹道.给出了限制脉冲点火的约束条件,在理论上证明了在点火约束条件下弹道导弹沿着脉冲弹道飞行能命中被打击目标并且不会被敌方拦截.给出了一个仿真实例.仿真结果显示,用该文方法设计出来的弹头机动弹道具有好的突防效果,这说明所提出的弹头机动弹道设计方法是可行的.
Based on the impulse trajectory transfer, a method that a ballistic missile breaks through the defense line was presented. The trajectory designed by the method consists of several ellipse curves, which is different from the classical trajectory and the trajectory of the missile maneuvers designed by other methods. The constraint conditions to restrict the impulse firing were given, and theoretically it is proved that the ballistic missile flying along the impulse trajectory can hit the target and is not intercepted by enemy under constraint conditions. An example of the numerical stimulation was given. The result shows that the trajectory of the missile maneuvers designed by the method can improve the capacity to penetrate the anti-missile system, and the method is feasible.
