基于相对运动考虑海流影响的拦截弹布放方法

为了提高海流影响下的悬浮式深弹拦雷概率,建立了海流使悬浮式深弹布放位置产生偏移的简化模型,分析了采用非标准射击条件修正方法进行海流修正的不足,进而提出了基于相对运动的海流修正方法,计算得到了考虑海流影响下的悬浮式深弹布放参数;然后通过计算机仿真理论验证了是否考虑及修正海流影响对悬浮式深弹拦雷效果的影响。 结果表明:当鱼雷报警距离为远,海流流速为 3 kn 时,修正海流影响能够使悬浮式深弹的拦雷概率提高 10% ~20%。

Laying Method of Interceptor Considering Ocean Current Influence Based on Relative Motion

In order to improve the torpedo interception probability of the suspended depth charge under the influence of ocean current, this paper establishes a simplified model of ocean current to offset the placement certificate of suspended depth charge, analyzes the shortage of ocean current correction by using nonstandard shooting condition correction method, then presents a method of ocean current correction based on relative motion, calculates the parameters of the suspended depth charge under the influ- ence of ocean current; verifies theoretically whether to consider and correct the influence of ocean current on the torpedo interception effect of suspended depth charge by computer simulation. The results show that when the torpedo alarm distance is long and the cur- rent velocity is 3 kn, the interception probability of the suspended depth charge can be improved by 10% ~ 20% by correcting the in- fluence of current.
