Research on efficiency evaluation for underwater acoustic countermeasure system based on grey hierarchy analysis

In order to solve the disadvantages for the efficiency evaluation of the underwater acoustic countermeasure, resulting from the underwater information fuzzy and data scarcity, the gray analytic hierarchy evaluation method is proposed. These disadvantages are classified based on the attribution, according to the mission, structure and function of the underwater acoustic countermeasure. And then, the efficiency evaluation index system of the underwater acoustic countermeasure system is established. Moreover, the concrete evaluation process for various situations are given. Finally, the simulation results show that the method can realize the quantitative analysis of efficiency evaluation on different countermeasure strategies, which provde a reference foundation for optimization of underwater acoustic countermeasure strategies.
