ATT对声自导鱼雷拦截方式变更的临界雷舰距离

对潜射声自导鱼雷的拦截是舰载反鱼雷鱼雷(ATT)拦截运用的一个重要内容。首先,针对潜射声自导鱼雷的直航搜索段和自导追踪段弹道特征,分析了ATT的拦截原理,指出ATT应采取不同方式实施拦截。其次,提出了ATT拦截方式变更的临界雷舰距离的概念,并按照本舰采取停车规避、保持原状态航行和采取转向远离规避3种典型态势进行了理论推导和仿真标绘。最后,围绕临界雷舰距离进行了数值仿真和规律分析。研究结果表明:临界雷舰距离是客观存在的,且随着本舰采取机动策略的不同呈现一定规律性变化。该研究结果可为ATT的实际运用提供参考

Critical Distance of Intercepting Mode Conversion of ATTAgainst Acoustic Homing Torpedo

It is an important content to intercept sub-launched acoustic homing torpedo in application research of ship-borne anti-torpedo torpedo(ATT). The intercept principle of ATT was summarized against direct searching trajectory and homing tracking trajectory of sub-launched acoustic homing torpedo. It was pointed that different intercepting modes should be adopted. A concept was proposed on critical distance while ATT attack mode was changed,and theoretical derivation and simulation plotting were carred out according to three typical situation such as stopping,navigating keep original state and turning away from torpedo. The numerical simulation and law analysis on critical distance were carried out. The research result shows that the critical distance is objective,and its change is regular partly with the evasion maneuver mode of surface ship. The result can offer reference for the practical application of ATT.
