摘要: 潜艇转向旋回对敌鱼雷自导检测有重大的影响, 是防御声自导鱼雷攻击的主要方式。文中基于声呐方程, 分析了潜艇转向后我舷角与敌鱼雷声自导作用距离的关系, 并在分析主动声自导鱼雷运用方位走向与亮点分布进行体目标识别的原理基础上, 构建了仿真计算模型。算例表明: 潜艇转向旋回可极大地缩短敌鱼雷声自导作用距离, 在转至大、小舷角时将误导敌鱼雷体目标识别错误使其转入对抗规避弹道。最后对实战中潜艇运用转向旋回战术防御主动声自导鱼雷的实施方法进行了讨论。文中所做研究可为潜艇指挥员进行鱼雷防御作战与鱼雷设计人员进一步研究鱼雷抗干扰策略提供参考。Abstract: The steering cycle of a submarine has great influence on homing detection of an enemy torpedo, and it is the main way to defend against an acoustic homing torpedo. Based on sonar equation, the relationship between the board angle of the submarine and the acoustic homing range of the enemy torpedo is analyzed after the submarine cycling. By analyzing the active acoustic homing torpedo’s principle of body target recognition using azimuth direction and highlight distribution, a simulation calculation model is constructed. Example shows that the submarine steering cycle can greatly shorten the acoustic homing range of the enemy torpedo, which will mislead the target identification of the enemy torpedo into the anti-evasion trajectory when the submarine is at the big or small board angles. In addition, the implementation method for a submarine to defend the active acoustic homing torpedo using steering cycle strategy is discussed. This research may provide a reference for submarine commanders to conduct torpedo defense operations and for torpedo designers to further study anti-jamming strategy of a torpedo.
