中文摘要：

对潜射鱼雷的综合防御技术是目前水面舰艇在鱼雷防御研究中需要重点解决的前沿问题。按照潜射鱼雷制导方式的不同，分直航鱼雷、声白导鱼雷、尾流自导鱼雷和线导鱼雷4种情形仿真鱼雷的弹道特征和攻击特点，并结合国际上常见的3种软杀伤器材、4种硬杀伤器材以及本舰规避机动策略，定性探讨各种对抗手段在综合防御鱼雷时的应用特点，分析并提炼战术运用一般规律。研究结果能够为水面舰艇综合防御潜射鱼雷提供重要的理论支撑和技术保障。

英文摘要：

The technology on synthetically defense against sub-launched torpedo is a front problem need to be mainly solved in surface ship＇s anti-torpedo research. According to the difference of guidance mode in sub-launched torpedo,the launching mode and the trajectory characteristics on straight-running torpedo,acoustic homing torpedo,wake homing torpedo and wire-guided torpedo are analyzed through simulation. Aiming at some familiar countermeasure equipments in the world including 3 sort of soft weapons,4 sort of hard weapons and surface ship＇s maneuver strategy,every sort of weapon＇s application method is analyzed qualitatively while defense against torpedo synthetically. Some rules on tactical application are analyzed and summarized. The result can provide theoretical and technological support for the action of surface ship synthetically defense against sub-launched torpedo.
