结合聚类分析的声速剖面战术分类技术

Technology on Tactical Classification of Sound Velocity Profile Combined with Cluster Analysis

声速剖面会显著影响潜艇产生的低频声信号的传播,以往声速剖面主要根据其数据梯度变化趋势进行划分,难以应用于作战决策。从应用角度,结合聚类分析方法,通过分析声速剖面对声场传播的影响,将声速剖面划分为浅海利于声信号远距离传播、浅海不利于声信号远距离传播、深海可形成会聚区、深海不可形成会聚区4种战术类型。该技术可用于水下预警和辅助决策领域。

The sound velocity profile can significantly affect the propagation of low-frequency acoustic signals generated by submarines.In the past,classification of the sound velocity profile is mainly based on its data gradient change trend,and it is difficultly applied in combat auxiliary decision-making.From the application perspective and combined with the cluster analysis method,the impact of the sound velocity profile on the sound field propagation is analyzed.The sound velocity profile is classified into four tactical types,including shallow sea conducive to long-distance acoustic signal propagation,shallow sea non-conducive to long-distance acoustic signal propagation,deep sea able to form a convergence zone,and deep sea unable to form a convergence zone.The technology can be applied in the fields of underwater early warning and aid decision-making.
