水面舰船对声自导鱼雷防御机动方法研究

A Study on Vessel Evading Method to Acoustic Homing Torpedo

根据水面舰船机动对其辐射噪声和反射强度的影响,首先建立了水面舰船与声自导鱼雷规避机动对抗的数学模型,然后采用Monte-Carlo法,计算水面舰船不同规避机动方法的生存概率,并分析了水面舰船转向、加速对其生存概率的影响,最后,得出水面舰船对声自导鱼雷防御的最优规避机动方法。提出的规避机动方法对水面舰船水下防御系统研究,具有十分重要的指导意义。

Based on the impact of vessel evasion on its radiant noise and reflect intensity, this paper firstly establishes opposition mathematics model of vessel evasion to acoustic homing torpedo, then adopts Monte-Carlo method to calculate survival probability of vessel in different evasion methods, and analyzes the impact on vessel＇s survival probability if vessel changes courses or speedups, and finally works out the best vessel evasion method to acoustic homing torpedo. The vessel evasion method introduced in this paper plays a leading role in the study of vessel underwater defense system.
