When a torpedo is coming towards a submarine,it may launch mobile acoustic decoy to improve defence effect.According to the countermeasure procedure of submarine launching mobile acoustic decoy to fight against the torpedo,optimized trajectory model of mobile acoustic decoy,maneuver evasion model of submarine,search and attack trajectory model of torpedo and acoustic detection models in countermeasure course were built,and on this basis the parameters of direct sailing turn-corner trajectory of mobile acoustic decoy on submarine's survival probability were simulated and analyzed.The results show that by properly designed direct sailing distance and turn angle it can improve submarine's survival probability obviously.
