研究超视距导弹中制导末段利用导弹的剩余动力 ,自动搜索活动目标 ,使目标捕捉概率达到最大的最优搜索问题 .给出了活动目标的位置概率分布 ;提出了基于活动目标位置概率分布的导弹搜索航线的规划方法 ;拟订了搜索系统的组成方案并对系统进行了设计 ;对该系统进行了仿真 ,验证它的活动目标的捕捉概率 . This paper studies the remaining power of the guided missile in the missile at the last guidance stage and automatically searches for the active target so that the optimal target capture probability is achieved.The optimal probability distribution of the active target is given.The probability distribution of the target based on the active target is proposed Of the missile search route planning method; developed a search system composition scheme and the system design; the system was simulated to verify the capture of its active target probability.
