摘　　要：反舰导弹在执行火力打击任务时,受制于末制导雷达性能、目标位置误差、敌方干扰等因素的影响,往往需要多次开机搜索目标位置以规避敌方的干扰和探测。论文针对反舰导弹多次搜索策略下对编队目标的捕获问题,提出了改进的反舰导弹搜索模型,该模型充分考虑了编队目标的散布特性和反舰导弹自控终点的初始误差,从而更贴近于导弹实际应用背景。通过研究末制导雷达搜索角度对编队目标捕获概率的影响,分析得出末制导雷达保持较高捕获目标概率与较低被敌方干扰概率条件下,对典型编队目标的最小搜索角度可缩小至42°。同时,研究了不同编队目标初始攻击舷角对编队目标捕获概率的影响,因此可以根据编队目标的航向合理选择导弹发射的初始攻击舷角,从而提高对编队目标的捕获概率。研究结果对于提高编队目标的捕获概率且降低被敌方探测的概率具有一定的理论指导意义。Anti-ship missile often needs to start up repeatedly to search the target position to avoid the interference and detec⁃tion of the enemy when performing firepower strike tasks due to a lot of factors such as terminal guidance radar performance,target position error and enemy jamming.Focusing on this problem,an improved search model of anti-ship missile is proposed to solve the complication of formation target acquisition under the multi-search strategy of the anti-ship missile.With the purpose of being clos⁃er to the practical application background of the missile,the model fully considers the dispersion features of the formation target and the initial error of the automatic terminal point of the anti-ship missile.Besides,the impact of the searching angle of the terminal guidance radar on the acquisition probability of the formation target is investigated.It indicates that the minimum searching angle of the typical formation target can be reduced to 42°under the condition that the terminal guidance radar keeps a higher acquisition probability of the target and a lower probability of being disturbed by the enemy.Meanwhile,the influence of the initial attack angle of different formation targets on the acquisition probability of formation targets is explored.Therefore,the initial attack angle of the missile can be selected reasonably according to the course of formation targets,contributing to the improvement of the acquisition probability of the formation targets.Furthermore,the research results have a certain theoretical guiding significance for improving the acquisition probability of formation targets and reducing the probability of being detected by the enemy.
