中文摘要：

为解决航空子母弹抛撒点抛撒高度、速度等参数设定问题，基于一种子弹单圈多段排布的航空子母弹模型，通过建立子弹的外弹道方程，研究它的地面散布并且寻找其散布规律；然后根据在实战中要求的所要摧毁的目标形状、面积，从子母弹作战效能角度出发，提出一种搜索算法，用该算法能搜索出覆盖目标范围所要求的子母弹的几种抛撒参数。仿真验证表明：该算法能够使子弹有效地覆盖目标，最大误差2．5％，提高了航空子母弹的作战效能。

英文摘要：

In order to get the key parameters of the Projectile Point of the sub-warheads, the external trajec-tory equation of bullets is constructed and the rule of the cluster warhead＇s fall point is analyzed based on a model of warhead with sub-warheads and the structure of excessive segments arrangement. This paper proceeds from the operational effectiveness, elects a search algorithm based on the shape and area of tar- get. After simulation investigation, the use of this algorithm can ensure that the warheads effectively cover the whole area of the target, and the maximum error is only 2.5 %. Therefore, the algorithm is efficient in improving the operational effectiveness of the shrapnel, and also can provide a new thought for the use and the development of the shrapnel.
