子弹圆环内散布子母弹对圆目标的毁伤概率

摘要

For the research on damage probability of cluster ammunition to circular target under situation of bomlets distribu⁃ted uniformly in annulus, the paper studies the covered area of a circular target by dispersion scope of bomlets under uniform distribution in an annulus firstly, then using the method of probability analysis it introduces calculation formulas of damage probability of cluster ammunition to circular target on single⁃shot and correlation fire while bomlets distributed uniformly in single annulus, and discusses the calculation method of damage probability on single⁃shot and correlation fire while bomlets distributed uniformly in multi⁃annulus. The example shows damage probability of cluster ammunition to a circular targe under bomlets distributed uniformly in double annulus is higher than that under in single annulus.%为研究子弹圆环内均匀散布的情况子母弹对圆目标的毁伤概率，首先研究子弹散布范围覆盖圆目标的面积，然后用概率分析的方法推导出了子弹单圆环均匀散布下子母弹单发射及相关射击对圆目标的毁伤概率计算公式，并讨论了子弹多环均匀散布下子母弹毁伤概率的计算方法。算例表明子弹双圆环内均匀散布时，子母弹对圆目标的毁伤概率要略高于子弹单环对圆目标的毁伤概率。
