Research on hierarchical parameter optimization method of underwater acoustic countermeasure strategy

The underwater acoustic countermeasure strategies concern a variety of factors, and have no analytical optimal solution. A method of optimizing the underwater acoustic countermeasure strategy using hierarchical parameters was proposed. Firstly, the hierarchical parameters were determined according to the effect of each parameter in oppositional process. Secondly, the hierarchical parameters were optimized through exhaustive simulation. Finally, the underwater acoustic countermeasure strategy was optimized. This method requires less computation than the exhaustive simulation method and eliminate the pseudo-optimal strategies which have no meaning in practical countermeasure.
