巡航导弹飞行撞地概率的一种计算方法

研究了巡航导弹飞行高度控制系统对应的高度控制误差和地形起伏误差,在综合这两种误差的基础上,提供了一种飞行撞地概率的计算方法,并给出了飞行高度与之对应的撞地概率计算实例。计算和分析得出,参考航迹高度取现行标准值的某型巡航导弹撞地概率太大,需通过减小高度探测控制系统的误差或者增大参考航迹的规划高度来降低撞地概率。

A Calculation Method of Bumping Ground Probability of Cruise Missle Flight

This paper studied height control error and terrain undulation error in relation to the height control system of cruise missile flight.A calculation method of bumping ground probability of the flight is presented and at the same time the calculation example of bumping ground probability in relation to flight height is also given in the paper.It is educed by calculation and analysis that bumping ground probability of some type of cruise missiles is too big when the reference track height takes the present standard value.It is necessary to reduce the bumping ground probability by reducing the error of a height detection control system or increasing the layout height of reference track.
