基于遗传算法的机动弹头再入段弹道优化设计

针对机动弹头攻击区优化问题,设计了改进遗传算法加约束可变多面体法的串行混合遗传算法,采用直接优化方法,基于分段优化思想,对再入段最大纵程、最小纵程和最大横程等边界弹道分别进行了优化设计,得到了满足约束条件的最优边界弹道,从而确定了机动弹头的最大可攻击范围.优化结果表明,最大可攻击区范围是一个长半轴为17 km,短半轴为10 km的椭圆区域,此结果优于针对该弹头进行的大量弹道仿真所得的结论,可为进一步弹道设计提供参考依据.

Optimization Design of Reentry Trajectory for Maneuverable Warhead Based on Genetic Algorithms

Aiming at the optimization problem of attack area of maneuverable warhead,an Aerial Hybrid Genetic Algorithms(AHGA) consisting of Genetic Algorithms(GA) and Constrained Flexible Polyhedrow Method(CFPM) was designed.By AHGA,maximal longitudinal range,minimal longitudinal range and maximal lateral range of reentry trajectory were directly optimized based on subsection optimization.Through the optimization work,the optimal boundary trajectory satisfying all rigid restrictions were got,and the maximal attack ar...
