摘要
利用主动吊放声纳与被动浮标组成多基地航空声纳对目标进行搜索,可节约搜索时间,有效提高搜潜效率。针对已知目标的大概航向,在有限范围内确定目标存在区的情况下,建立了多基地搜潜范围模型、单机吊放声纳和浮标的主/被动联合多基地搜潜模型、潜艇运动模型,仿真分析了潜艇初始航向、海洋环境噪声、搜索样式等因素对联合搜索概率的影响。结果表明,潜艇初始航向角度对单机吊放声纳和浮标的联合搜索概率影响较小,海洋环境噪声的变化对单机吊放声纳和浮标的联合搜索概率影响较大。
The use of multi-station aeronautical sonar composed of an active dipping sonar and passive buoys can save search time and improve search probability. In view of the demand to determine the area where the submarine target exists in a finite domain according to a probable known moving course of the target,this article proposes a search scope model of the multi-station sonar,a search model of the combined active/passive multi-station aeronautical anti-submarine of dipping sonar and buoys,and submarine moving models. It simulates and analyzes the influence of such factors as submarine initialization courses,sea environment noises as well as search manners on the searching probability in the experiments. The results show that submarine initialization course has comparatively little effect on the combined aircraft searching probability of a dipping sonar and buoys,while the factor of sea environment noises has a greater effect on it.
