Objectives Under existing technical conditions, fleet formation is optimized in order to improve the cooperative detection performance of a fleet against hostile submarines.
Methods The coverage index is defined as a measure of submarine detection ability. Taking a naval combat formation for antisubmarine warfare as the research object, based on the theory of the probability formula of the joint detection performance of multiple ships and taking the maximization of the coverage area as the goal, a formation optimization model based on antisubmarine detection ability is established. An integral optimization method based on the probability distance function is designed to solve the model, and a reasonable formation scheme is obtained.
Results The simulation results show that the coverage area changes regularly with the variation of the distribution distance of the ship. Under the same fleet size, the detection performance of herringbone formation or wedge-shaped formation is better than that of a single horizontal formation or azimuth team formation under optimal distribution spacing. In addition, the optimal distribution spacing decreases with the increase of the detection probability threshold. As the scale of the fleet increases, the coverage area increases correspondingly in a linear manner.
Conclusions This model can effectively improve the capability of fleet searching and provide a decision basis for the use and deployment of surface ships in a potential search force.
