体目标条件下反潜鱼雷命中目标模型

Target hit model of anti-submarine torpedos based on target-body

针对反潜鱼雷末弹道精确仿真要求,提出将反潜鱼雷与其攻击目标同时作为体目标的方法。通过确定3个基本坐标系,建立了反潜鱼雷与其攻击对象相应的三维体目标模型,在此基础上推导了基本坐标系之间的坐标变换矩阵。通过分析反潜鱼雷末弹道特性,推导了命中目标的判断过程与实现流程,同时定义了相关命中目标要素。仿真计算结果表明:该模型能够真实模拟反潜鱼雷在末弹道对其攻击目标的攻击过程,准确判断反潜鱼雷对目标的命中情况,实现对命中概率、各舱段命中概率、触发与非触发命中概率、爆炸中心脱靶量等命中目标要素的精确计算。

According to the requirements of precise simulation of terminal trajectory,anti-submarine torpedoes and the targets to be attacked was considered as the target-body at the same time.Then a three-dimension model was established.The model helped derive the hit objective judgment process and implementation process.The simulation analysis shows that the model can simulate the process of the anti-submarine torpedoes attacking the targets at the terminal trajectory to realize the accurate calculation of the hit probability,the cabin hit probability,trigger,and non-trigger hit probability and missing distance of the explosion center.
