为提高舰载反潜直升机吊放声纳区域反潜搜索作战效能,对舰载反潜直升机吊放声纳区域反潜搜索策略问题进行了建模。根据潜艇目标位置信息的不确定性,研究了潜艇目标位置信息的概率分布函数,采用Markov状态转移概率矩阵描述了潜艇目标位置信息变化的方法。其次,给出了基于贝叶斯理论的潜艇目标信息概率分布函数更新公式。再次,推导了舰载反潜直升机吊放声纳区域反潜最优策略,给出了舰载直升机吊放声纳区域反潜搜索算法。最后给出了典型案例,验证了反潜搜索策略的有效性。研究成果可为舰载反潜直升机吊放声纳区域反潜提供决策依据。

Modelling and Research on Area Searching Strategies for Antisubmarine Helicopter With Dipping Sonar

In order to improve operational efficiency of area searching for antisubmarine helicopter with dipping sonar,the area searching strategies for antisubmarine helicopter with dipping sonar is modeled and researched. Firstly,because of the uncertainty of submarine position information,the probability density of submarine position is researched,and the Markov transition probility matrix is used to describle the motion of helicopter. Secondly,the new submarine position probability is updated using bayes rule. Thirdly,the optimal search strategies for antisubmarine helicopter with dipping sonar is deduced,and the search algorithm is given. Finally,experimental results demonstrate the ability and validity of the optimal search strategies. The results of this paper can provide decision support for area searching of antisubmarine helicopter with dipping sonar.
