摘要: 研究了巡航导弹低空地形跟踪飞行的撞地概率问题.在考虑了地形随机输入和低空风随机干扰共同作用的情况下,针对导弹长时间超低空地形跟踪飞行这一特点,研究了撞地概率的计算方法.又以导弹主要参数静稳定性动力系数a24和高度反馈系数Kh为例,在给定条件下求出了它们和撞地概率的关系曲线,分析了它们对撞地概率的影响.从中可以看出,协调选择a24和Kh等参数,能有效降低撞地概率,提高巡航导弹的作战效能.

Abstract: This work studies the probability of clobber(Pc) of a cruise missile's low height terrain following flight. It deduces the computation method of the clobber probability, puts forward a set of practical formulas for computing the probability of clobber, while taking the influences of both the random input of terrain and the random interference of wind at low height, and the characteristically long-time very low height terrain following flight of missile into consideration. Using them and taking the parameters a24 and Kh as an example, under given condition, the correlative curve of the parameters and the probability of clobber is worked out, the parameters' influence on the probability of clobber is analysed. The conclusion is that, to co-ordinate the parameters such as a24 and Kh can reduce the clobber probability effectively, and at the same time enhance the warring capability of the cruise missiles.
