Influence of Negative Gradient Sound Velocity Profile on Anti-ship Effect of Active Acoustic Homing Torpedo

摘要: 鱼雷主动声自导反舰效果不仅和其自导系统性能有关, 还和声速剖面特性有着密切的关系。针对我国浅海海域普遍存在的负梯度声速剖面, 分析其对声线传播特性的作用机理, 得出负梯度声速剖面可能导致鱼雷主动声自导反舰失效、自导作用距离缩短与跟踪目标不连续, 从而影响鱼雷主动声自导反舰效果。最后结合具体算例进行分析说明。文中的研究可为进一步提高主动声自导反舰鱼雷使用效能提供依据。Abstract: The anti-ship effect of an active acoustic homing torpedo depends on the performance of acoustic homing system and the sound velocity profile characteristics. Aiming at the negative gradient sound velocity profiles in the shallow sea areas of China, this paper analyzes the effect mechanism on sound ray propagation, and concludes that the negative gradient sound velocity profile may lead to attacking failure of active acoustic homing anti-ship torpedo, shortened homing distance, and discontinuous target tracking, which will affect the anti-ship effect of active acoustic homing. Finally, an example is given. This research may provide the basis for further enhancing effectiveness of active homing anti-ship torpedo.
