潜艇纯机动防御两枚声自导鱼雷数学模型研究

A Mathematical Model for the Submarine to Maneuver Defending Double Acoustic-homing Torpedoes

现代潜艇作战对多枚鱼雷的防御问题是一个急需解决的课题。在潜艇防御主动声自导鱼雷原理的基础上，建立了潜艇防御两枚声自导鱼雷的优化模型，通过仿真计算得到了在取得最佳防御效果时鱼雷舷角和两枚鱼雷航向差的关系，以及潜艇最佳防御效果与两枚鱼雷航向差的关系。并结合潜艇防御战术，得到潜艇防御过程中将两枚鱼雷中一枚鱼雷置于艇首或艇尾，以及潜艇可以采取机动的措施使鱼雷发射平台机动以避免来袭鱼雷航向差在90°附近的结论。

Studying on the submarine defending double torpedoes is the purpose in this article. Based on the principle of the submarine defending an active acoustic-homing torpedo, the optimization model about the submarine how to defend double acoustic-homing torpedoes is built. And the relationship between the board angle and the course dispersion of double acoustic-homing torpedoes when getting the optimal recovery effect, as well as the relationship between the optimal recovery effect and the course dispersion of double acoustic-homing torpedoes are achieved through computer simulation. A conclusion is drawn that the submarine can get one of the acoustic-homing torpedo been its head or tail, as well as to make the fire-bed of torpedo maneuver to avoid the course dispersion of double acoustic-homing torpedoes reaching 90°.
