Influence of Sonar Detection on Detection Probability of Submarine Torpedo Weapon System

When a submarine launches a wire guided torpedo in a hidden mode to attack a surface target, the front sonar detection ability of a weapon system significantly affect the detection probability and attack effect. This paper analyzes several sonar target detection factors influencing the detection probability, establishes a model by suing the present bearing guidance method and simulate the torpedo attack of the weapon system. Simulation reveals the change ruler of weapon system′s detection probability in the case of different torpedo initial attack distance and instable target tracking, and corresponding strategies and methods are given to provide a reference for torpedo attacking and engineering practice.
