Simulation on Detection Probability of Submarine-Launched Homing Torpedo Based on the Optimized Firing Model

The firing triangle is the theoretical basis for calculating the firing advance angle of submarine-launched torpedo. With the development of torpedo technology and the need of battlefield, the application of traditional torpedo firing triangle becomes more and more limited. In this paper, the effects of torpedo velocity variation and target radiated noise on torpedo homing distance are considered, and an optimization model of the firing elements of submarine-launched acoustic homing torpedo, which is close to actual combat, is established, and a method for calculating the advance angle is deduced. According to this model, simulation of torpedo attack trajectory and calculation of detection probability are conducted, and the results show that this model is applicable to comprehensive battlefield situations.
