Influence of Water Conditions on Torpedo Acoustic Homing Range

Aiming at forecasting the torpedo acoustic homing range for actual targets under real water conditions, this paper summarizes the typical water conditions in different sea spaces and seasons, presents a forecast method of torpedo acoustic homing range, and establishes a transmission loss forecast model based on the ray acoustic theory and a reverberation level forecast model based on the cell scattering model. According to the technical parameters of acoustic homing torpedo, the torpedo acoustic homing range of actual targets under real water conditions is forecasted with the grid search technique. This paper also proposes some suggestions for commanders to attack targets with torpedoes.
