基于灰色关联的来袭鱼雷制导方式识别

Guidance type identification based on gray correlation analysis for incoming torpedo

准确识别来袭鱼雷制导方式是水面舰艇在鱼雷防御过程中采取有针对性对抗措施的前提。本文分析直航鱼雷、声自导鱼雷、尾流自导鱼雷和线导鱼雷在潜艇攻击征兆、鱼雷齐射数量、航速变化次数和累积方位变化量上的差异,选取这4个变量作为特征指标,运用灰色关联分析法建立来袭鱼雷制导方式识别模型。计算实例证明该方法的有效性,可为水面舰艇的鱼雷防御提供有益参考。

Exact guidance type identification of an incoming torpedo is a premise for surface ship to defend against torpedo pertinently. In this study,the differences between straight-running torpedo,acoustic homing torpedo,wake homing torpedo and wire-guided torpedo in submarine attack symptom,number of torpedo volleyed,speed change times and cumulative azimuth variation are analyzed. Choosing the four variables as characteristic indexes,the guidance type identification model is established by using gray correlation analysis. It is verified by experiments that the method is effective and it can provide helpful references for surface ships＇ defense towards incoming torpedo.
