Abstract: 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.
