Multiple Anti-submarine Helicopters' Cooperative Front Submarine Detecting Research

This paper is aiming at solving the problem of front submarine detecting combat of multiple ship-borne anti-submarine helicopters in the process of naval warship formation. By analyzing the launch range of submarine-launched torpedo, torpedo attack launch position models are established under two conditions of ideal condition and formation evasive maneuver, and the position configuration of front submarine detecting area is obtained. On this basis, multiple helicopters front submarine detecting methods are analyzed in the process of formation flight, and front submarine detecting force demand and probing probability model are established. Finally, the influence of the submarine-launched torpedo launch position, anti-submarine force size, the number of detection and the size of front submarine detecting area on the probability of discovery is calculated. The results show that it is appropriate when front submarine detecting area is 20 nautical miles in the front of the formation, 20 * 30 nautical miles size, and three anti-submarine helicopters.
