摘要
对来袭鱼雷弹道进行预测是实施鱼雷防御的一个前提条件。首先,分析了目前水面舰艇对鱼雷信息的获取方式与特点,指出应以鱼雷方位信息为基准进行弹道预测。其次,从不同类型潜射鱼雷的发射方式和弹道特征着手,分别建立了潜射直航鱼雷、声自导鱼雷、尾流自导鱼雷的弹道预测模型,并归纳了线导鱼雷的导引艇方位分布规律。最后,通过仿真分析不同类型鱼雷的弹道预测效果和影响因素,并定量给出了线导鱼雷的导引艇方位预测偏差范围最小可达3°～5°。该研究成果可有效提高水面舰艇的鱼雷防御效能。
Predicting the coming torpedors trajectory is one of preconditions of defense against torpedoes. Firstly, this paper analyzes the modes and characteristics of a surface ship detecting a torpedo, and points out the torpedo trajectory prediction should be based on the information about torpedo＇s azimuth. Secondly, according to the launching modes and trajectory characteristics of different types of torpedoes, prediction models for straight-running torpedo, acoustic homing torpedo and wake homing torpedo are established. The azimuth distribution of a submarine wire-guided torpedo is deduced. Finally, the trajectory prediction effects and influential factory of different types of torpedoes are analyzed through simulation. The submariners azimuth distribution range is provided quantitatively. The result of simulation shows that a surface ship can improve its efficiency in defense against torpedoes.
