This paper analyzes the trajectory characteristic of missile, and the building target to be hit is equivalent to the ground projection. Based on the characteristics of building target, we proposes a shooting method synthesizing both accuracy and obliquity of trajectory, and proves the theory that point of fall is the centre of projection. The hitting probability model is proposed and hitting probability method is deduced. An example concerning typical target is presented using the proposed method. According to the calculating results, influences on the hitting probability by accuracy, height, obliquity of trajectory and direction angle are analyzed. The results show that the proposed method is reasonable and feasible.
Key words: missile; hitting probability; firing error; obliquity of trajectory
