Analysis on Parameters Influencing Intercept Probability of Anti-torpedo Torpedo

To understand the major parameters which influence intercept probability of ananti-torpedo torpedo (ATT), we establish a torpedo trajectory model and a ship evasion model based on assumptive intercept state. According to the calculation results, we quantitatively analyze the effects of detection error, homing range, and homing sector angle on intercept probability of ATT. Simulation results indicate that the intercept probability of ATT can be effectively improved by raising locating accuracy of coming torpedo, and increasing homing range and homing sector angle of ATT.
