炮射子母弹子弹散布幅员远大于单个目标毁伤幅员。为提高计算效率及便于子弹的最佳散布范围和子母弹最有利火力分配方法研究,用概率分析的方法建立了单发射击和以相同诸元发射若干发弹时相关射击炮射子母弹对小尺寸矩形目标和圆形目标毁伤概率近似计算数学模型;讨论了仿真计算的方法;推导了对小尺寸矩形目标和圆形目标射击炮射子母弹最佳散布范围。给出了对矩形目标和圆形目标毁伤概率的算例。子母弹毁伤概率近似计算数学模型便于理论研究,便于计算,与精确模型相比两者毁伤概率的计算结果相差很小。
Artillery submunition shells scatter much larger than a single target destruction width. In order to improve the calculation efficiency and the best distribution range of the bullets and the most favorable method of fire distribution for the submunition, the method of probability analysis was used to establish the correlation between the single shot and the firing of several bullets in the same element. The mathematical model of approximate probability calculation of the target and circular target damage probability is discussed. The method of simulation calculation is discussed. The optimal distribution range of small rectangular target and round target target projectile is deduced. An example of the probability of damage to a rectangular target and a circular target is given. The approximate mathematical model of the probability of damage to a bomblet is convenient for theoretical research and is easy to calculate. Compared with the exact model, the calculation results of the damage probability of the two bombs are quite small.
