基于弹着点椭圆散布的射击方位角选取∗

摘要

Based on ellipse dispersion of ballistic missile point, a model selecting of the hit probability was. As rectangular target, the best can be directly selected out through formula traversal screening. As common target, particle swarm optimization ( PSO) algorithm searching the best. The results of calculation showthat:as larger aspect ratio target, it could be directly to maximize hit probability by axial shooting. As smaller aspect ratio target and general area target, it could get the best by making use of formula traversal screening and PSO algorithm.%根据弹道导弹落点椭圆散布规律，构建射击方位角选取模型。针对矩形目标，可直接通过公式遍历筛选；而针对一般面目标，提出用粒子群算法搜索最佳射击方位角。实例计算结果表明，大长宽比目标轴向射击命中概率最大；而针对小长宽比目标和一般面目标，可通过公式遍历筛选和粒子群搜索算法选取最佳射击方位角。
