Calculation Method of Torpedo Discovery Probability by Combining Analytical and Simulation Methods

Abstract

The analytical method and simulation method are commonly used to calculate the discovery probability of acoustic homing torpedoes. The analytical method is fast but only applicable to some parameter error types. The simulation method is applicable to all parameter error types, but its calculation efficiency is low. To address this issue, a torpedo discovery probability calculation method combining analytical and simulation methods was proposed. Firstly, the parameter masking interval was solved based on the simulation method. Then, the discovery probability was calculated using the analytical method, which significantly improved calculation efficiency while ensuring accuracy. Finally, the effectiveness of the proposed algorithm was verified through simulation.
