一种控制力大小自由的弹道导弹机动方案探讨

Study on a Ballistic Missile Maneuver Method of Free Control Force

基于虚拟目标点和椭圆弹道理论,提出了一种在自由段机动变轨的新方法。该方法只需在恰当的时机进行一次变轨机动就能在不改变导弹命中精度的前提条件下,完成变轨突防。不仅如此,该方法中,提供机动的控制力的大小在小量范围内是自由的,这样就不会因为机动时控制力的精度影响导弹落点的精度。

Based on the virtual target point and the ellipse trajectory theory,a new maneuver method in the free- flight phase is presented.Using this method,the missile only needs once maneuver to succeed to evade the interceptor at the suitability time and the hit probability is not reduced.Moreover,the strength of the control force is free.So,the control force error has no effect on the impact point error.That is important to reduce the impact point error after the missile maneuver.
