英文摘要：

According to the basic principle and the typical situation of the anti-underwater vehicle countermeasures for underwater targets, a target position distribution model under target prevents underwater vehicle by random maneuver and the one by maneuver with countermeasures wereaddressed, based on normal distribution. The position information under certain attack station was re- corded by using the antisubmarine underwater vehicle simulation system, which could exactly reproduce underwater vehicle attacking process and keep down the trajectories of all the moving. The recording present that the distribution model fall in with the simulating result and it is the proof of theeffectiveness and rationality of the distribution model. Therefore, the model can be further used to analyze the operational effectiveness for antisubmarine underwater vehicles or design underwater vehicle＇s general trajectories and homing search strategies.
