多机吊放声纳对潜警戒扇面动态计算方法

针对多架反潜直升机使用吊放声纳搜索时的对潜警戒扇面动态计算问题,根据搜索方法建立多机悬停点坐标解算模型;采用等效的方法,将当前悬停点吊放声纳的探测区域与所有已完成探测的悬停点不存在潜艇的区域等效为对潜警戒范围进行计算;建立了各悬停点探测区域相对舰艇编队舷角的动态计算模型;给出了动态计算多机对潜警戒扇面起始、终止舷角的计算方法。最后仿真计算了对潜警戒扇面随搜索时间、间距系数的动态变化关系。结果显示:对潜警戒扇面将在一定范围内周期性动态变化;且受间距系数的影响较大。

Dynamic Calculation of Warning Sector for Multi-helicopter Anti-submarine Search with Dipping Sonar

Aiming at multi -helicopters anti -submarine search with dipping sonar,dynamic calculation method of warning sector is investigated. According to search method,model is built to resolve the position of detecting points for every helicopter. It considers the search coverage at current detecting point and that have detected but not found submarine as submarine warning area. It builds the dynamic calculation model for the bearing relative to ship formation,including the starting and terminal bearing. Finally,it simulates the warning sector varying with searching time and spacing coefficient. Results show that warning sector will change cyclically in a certainty range;and which is influenced greatly by the spacing coefficient.
