Analysis of Acoustic Homing Torpedo Searching Threat Area

Against the background of acoustic homing torpedo attacks on surface ships, this study presents a definition of an acoustic homing torpedo searching the threat area, and then solves the threat range using an iteration method and an estimated method. From the perspective of surface ship defense, in the brief estimation of torpedo position and speed, the intuitively gives acoustic homing torpedo effective attack course range, to determine the threat area of torpedo, and provides a theoretical basis for torpedo defense decisions of surface ships. Compared to the experience estimate, the method in this study can effectively reduce the scope of the torpedo threat area, and embedding the algorithm in the ship fire control system can judge and display the threat area of the incoming torpedo in real time, increasing the efficiency of the surface ship undersea interception.
