Analysis on Attack Performance of Sleeping Torpedo

To improve the operational efficiency of a sleeping torpedo, an attack performance simulation model of a sleeping torpedo is established according to its technical characteristics of launching guidance and the given principle, situation and trajectory flow. The present bearing method and advance bearing method are used to calculate the detection probability when a multi-speed torpedo is running at alternate high and low speeds, and a speed setting scheme for effectively improving the detection probability of a sleeping torpedo is achieved. Aiming at the problem of large miss distance of a torpedo at big enemy board angle, the simulation results of two methods are compared, conclusion is drawn that the advance bearing method can improve detection probability more effectively for a sleeping torpedo.
