Research on an Optimized Method for Submarine Torpedo Attacking with Incomplete Information

The anti-submarine ability of the warship improved quickly as the increasing threat of the submarine. On the other hand, the submarine commander should make tactical decision quickly and accurately under high threat environment. This fact means that not only should be launch torpedo snugly, quickly and accurately, but also make this decision with incomplete target information. This paper takes a new approach to find the possibility distribution of the target with limited information. Based upon the results, particle swarm optimization method was applied to find the optimized torpedo advance angle. A test-bed was constructed to demonstrate the process of torpedo attacking and validation of the optimized method. Simulation results illustrated that the optimize torpedo advance angle exist and could cover a wide scope of target movement information error. Thus provides the submarine commander an optimized method to use torpedo in such a situation.
