多机吊放声纳应召搜潜建模与仿真

 依据经典的单机吊放声纳应召搜潜方法，结合实际搜潜过程，以4架反潜直升机为例建立了多机编队吊放声纳的扩展方形、扩展圆形、扩展螺旋形应召搜索模型和潜艇运动模型。对几种应召方法的搜潜效能进行分析，仿真了潜艇初始航向、吊放声纳作用距离、搜索样式等因素对应召搜索概率的影响。实验结果表明：潜艇航速、航向角度以及吊放声纳作用距离的变化对多机编队扩展方形、扩展圆形和扩展螺旋形应召搜索概率影响较大。使用多机协同应召搜潜，可在较短时间内进行大面积搜索，有效提高搜潜效率。

Model Building and Simulation Based on Definite Second Time Submarine Search by Multi-aircraft Dipping Sonar

According to classical definite second time search means of dipping sonar, and combining the actual process of submarine search, four-aircraft definite second time submarine search models of dipping sonar such as extended square search, extended circle search, extended spiral search and submarine moving models are built in this article. Moreover, we also analyze the submarine search performance of different means, and simulate the influence of the varieties of submarine initialization courses, search space of dipping sonar, search manners on search probability. The results show that factors such as submarine speed, course and search space of dipping sonar have a great effect on the first three models mentioned above. By using multi-aircraft associated search, more area can be searched in less time, and thus search efficiency can be improved.
