摘　　要：研究了巡航导弹的撞地概率和系统参数选择的关系问题。首先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，推导了撞地概率的计算方法。其次以导弹主要参数（ａ２４和Ｋｈ）的选择为例，在给定条件下求出了它们和撞地概率的关系曲线，并分析了它们对撞地概率的影响。研究结果表明，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。This paper studies the relation of the clobber probability and the parameters selection of the cruise missiles. It deduces the computation method of the clobber probability (PC),puts forward a set of practical formulas for computing PC,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 a24 and Kh as an example, under given condition, the correlative curve of the parameters and PC is worked out, the parameters' influence on PC is analysed. The conclusion which we reach is that, to coordinate the parameters such as a24 and Kh can reduce the clobber probability effectively, and at the same time enhance the warring capability of the cruise missiles.
