摘要: 主动声尾流自导鱼雷导引弹道的优化是在保证目标命中概率的前提下尽可能地降低鱼雷航程损失,提高鱼雷跟踪目标的相对速度以缩短攻击时间的一项关键技术。本文对三波束尾流自导导引方法进行了研究,分析了鱼雷首入尾流、首出尾流和再入尾流3个阶段弹道设计的目的、航向调整的模式以及关键参数的确定方法,给出了表述弹道优化效果的参数及其计算公式,并进行了数值计算,结果表明,在尾流内外对弹道所采取的调整方法能保证鱼雷航程损失较小,并可靠跟踪目标,可供主动声尾流自导鱼雷弹道优化设计参考。Abstract: The optimization of guidance trajectory for active acoustic wake homing torpedo is a key technology to reduce endurance loss and increase hit probability. This paper researches the guidance method of triple beams wake homing and analyzes the purpose of trajectory design, the mode of course adjustment, and the method for determining key parameters during three phases of torpedo trajectory of first wake entry, first wake exit and wake reentry. It also proposes the parameters and their formulae to describe the effect of trajectory optimization. The calculated results show that the proposed method can ensure less endurance loss and track accurately target.The method is expected to be used for the trajectory optimization design of active acoustic wake homing torpedo.
