鱼雷航向估计模型的可信性

Credibility Study of Torpedo Course Estimation Model

悬浮式深弹拦截鱼雷是大型水面舰艇水下防护作战的一种重要形式,其中估计来袭鱼雷的航向是实施拦截的关键。针对鱼雷航向的估计问题,引用基于相遇三角形原理的来袭鱼雷航向估计模型,分析了来袭鱼雷的可能航向角范围。采用数字仿真和仿真模型置信度的决策分析方法,对模型的可信性及其决策风险进行了量化分析。结果表明,该鱼雷航向估计模型可信,可为悬浮式深弹拦截鱼雷的作战训练、战法研讨及其仿真研究提供参考。

Intercepting torpedo using suspended depth charge is an important form of underwater warfare defense of large surface ships, in which the course estimation of the coming torpedo is the key point of interception. First, aiming at the problem of torpedo course estimation, torpedo course estimating model based on the principle of hitting triangle is quoted, and possible course angle range of torpedo is analysed. Then, digital simulation and the method of decision-making analysis about simulation model credibility are adopted, and the credibility and decision-making risk of the model are analysed quantitatively. The result shows that, the course estimation model is credible, and can provide consultation for the battle training, operation method discussion and the simulation research of intercepting torpedo using suspended depth charge.
