Simulation Method for Hitting Effect of Torpedo Attacking Body Target

The hitting effect of a torpedo is usually represented by the hitting parameters. However, evaluating hitting effect via point target can only get the miss distance, and eluding measures are often taken to prevent a torpedo colliding with an acoustic target or a real target in sea trial, the actual hitting parameters are difficult to be obtained. In this paper, a simulation method for evaluating torpedo hitting effect with body target is presented. A whole trajectory’s mathematical model of torpedo tracking target process and a mathematical model describing the geometric characteristics and hitting parameters of the body target are established. Simulation calculation and analysis on the hitting effect of a torpedo attacking body target are carried out. Simulation results show that the torpedo hitting effect is related to the geometric characteristics of the target, the target velocity, the relative situation between the torpedo and the target, and so on. This method may provide an effective means for evaluating torpedo hitting effect, and may provide a reference for optimization designs of torpedo trajectory and guidance law.
