摘　　要：空战仿真中,由于仿真系统采用时间帧周期方法调控系统的解算,致使导弹等武器的飞行弹道呈离散函数变化,而导弹等武器的飞行相对于靶标(运动或静止)是一个快速运动,这样,武器与靶标的碰撞解算就会引出很多误差问题。针对这个问题,建立了武器与靶标碰撞的适应度模型,提出了用启发式搜索方法检测碰撞点的算法。In the air combat simulation, since the system runs in the way of time frame cycle, the flying locus of the weapon, such as missile, changes as a dispersing function, and its movement is much faster than the target （moving or static） comparatively, so some errors emerge when the collision test is calculated between the weapon and the target. To solve such problem, an adaptability scale model of calculating the collision test between the weapon and the target was proposed, and further an algorithm to test the collision point with the method of heuristic search （HS）was brought forward.
