摘要
通过建立反潜机的方形、扇形和螺旋线形应召搜索模型,分析讨论了潜艇航速和航向的变化对吊放声纳搜索概率的影响,并进行了仿真比较。结果表明,随着潜艇航速、航向角度的增加,吊放声纳搜索概率不断下降,且航速、航向变化对螺旋线形搜索的搜潜概率影响要小于方形搜索和扇形搜索。同时也表明潜艇以远离当前吊放点为规避航向且全速规避时会明显降低吊放声纳的搜索概率,这对潜艇规避对抗吊放声纳搜索具有实际的指导意义。
The models of square search, sector search and spiral search were firstly established Based on the models, the effects of search efficiency of dipped sonar along with the changing moving velocities and courses of submarine were analyzed respectively. Lastly simulations results showed that searching probability of dipped sonar decreased with the increase of submarine＇s velocities and courses, and that the effect on the searching probability of dipped sonar was lesser than that of square search and sector search, and that when submarine evaded with full speed far away from the current dipped point, the searching probability would be reduced obviously. It was of practical guiding significance for submarine fighting against dipped sonar.
