摘　　要：能否准确有效地计算毁伤元对空中目标的着靶参数是评价弹药对空中目标毁伤概率的重要环节,也是评估导弹武器系统作战效能的重要指标.在分析毁伤元运动模型和目标元模型的基础上,提出了将圆柱形目标离散成多个小矩形并根据交会点到矩形四边的距离之和与周长关系作为命中目标的判定方法,推导出了着靶速度方向和目标轴截面、横截面夹角及着靶角和着速参数计算方法,并通过实例验证了该算法的正确性与准确性,为进一步研究毁伤元对目标的毁伤计算奠定了基础.Whether to calculate the impacting parameter accurately and efficiently which is about the kill element against the air target not only plays an important role in evaluating the kill probability of ammunition for aerial targets, but also plays an important indicator to assess the operational effectiveness of the missile weapon system. Based on the analysis of kill element and target motion model, methods of discreting cylindrical target into multiple small rectangles were proposed, and the angle calculation methods on the velocity direction of impacting and the axial section, cross section of the target, target angle and the target speed were deduced by using the judging criterion on hitting the target according to the relation between the distance of the intersection point to the four sides of the rectangle and the perimeter. And then the correctness and accuracy of the algorithm were verified by an example. The algorithm serves as basis for further studving the imoacting oarameter which is about the kill element a^ainst the aerial target.
