摘　　要：为了优化选择线导鱼雷发射阵位,掌握鱼雷的极限射距随目标舷角的变化规律,应用现在方位导引法仿真研究了线导鱼雷的攻击可行域。首先介绍了鱼雷导引系统的原理和特性,其次建立了现在方位导引法的线导鱼雷攻击弹道模型,详细说明了鱼雷攻击弹道的各阶段划分及相关数学模型,最后给出了鱼雷极限射距的含义和数学解析,并编制程序进行了仿真。通过实例分析表明,应用现在方位导引法的线导鱼雷攻击可行域近似一个前突的圆,采用小舷角从目标潜艇首部实施线导鱼雷攻击可以获得较大的捕捉和命中概率。整套方法系统量化了线导鱼雷发射距离及其攻击可行域,有效地解决了鱼雷攻击可行域这一关键问题,有助于提高线导鱼雷命中概率。To optimizes the choice of wire-guided torpedo launch station, analyze the rule of limiting attack-dis- tance varies with relative bearing and achieve the attack feasible region of wire-guided torpedo by using present bear- ing, this paper introduced principle and characters of the torpedo homing system, established wire-guided torpedo ballistic trajectory based on present bearing, illuminated in detail the divisions of the torpedo-voyage and the mathe- matical model of the torpedo voyage, and gave out the limit-distance of wire-guided torpedo. According to the analy- sis for an instance, the attack-feasible region of wire-guided torpedo simulation based on present bearing is similar to a circle, it can improve the capture and damage capabilities if wire-guided torpedo is launched from the bow of sub- marine. The method of this paper totally quantizes the attack distance and the attack-feasible region of wire-guided torpedo, solves the key technology of attack-feasible region, and improves the damage capabilities of wire--guided torpedo.
