提出了炮射子母弹子弹分布范围问题,给出子母弹对矩形目标和圆形目标的首发命中概率计算公式,以最大首发命中概率作为确定炮射子母弹子弹分布范围的分析方法。在一定的条件下计算了子母弹对6种尺寸的矩形目标和两种半径圆形目标的首发命中概率,根据最大命中概率确定其相应的子弹分布范围。子母弹子弹分布范围的讨论为子母弹作战使用研究提供了新思路。

A problem of distribution of cannon-launched cargo munitions was put forward, formulas for calculating first round hitting probability of sub munitions projectile on rectangular and circular target were given, the maximum first round hitting probability was applied to determine the preferred cargo munitions distribution range. Under a certain condition, first round hitting probability on six sizes of rectangular targets and on two radiuses of circular targets was calculated, and the preferred cargo munitions distribution range was analyzed by the maximum first round hitting probability. The discussion of preferred cargo munitions distribution range for cannon-launched cargo munitions provides a new concept for cargo munitions operation research.
