摘要
以破片杀伤战斗部的破片动态相对飞散密度函数作为设计变元 ,得到单枚导弹战斗部对空中目标的杀伤概率泛函。于是 ,对防空导弹引战配合的设计就转化为求解相应的变分问题 (VP)。通过里兹法对此进行了近似求解 ,求解结果与实际的引战配合情况完全符合。这说明防空导弹引战配合设计的变分法是可行的 ,从而为现代防空导弹引战配合在更广泛的类型中寻求最佳设计提供了有效的方法和手段。
This paper presents the kill probability functional of single missile warhead against air-target, taking the relative distributive density function of fragments along the lengthwise cutting-plane of fragmentation warhead case as the design variable, and applies the Ritz method to an approximate solution for the variational problem about the F-W coordination design of air-defense missiles. The computational results conforms to actual case of fuse-warhead coordination. Thus, this shows that the variational method is feasible and supplies an excellent tool for the modern F-W coordination design in the extensive patterns.
