doi:10.3969/j.issn.1000-1093.2018.05.017

摘要/Abstract

摘要： 对激光经气泡、水体散射后偏振特征的变化进行理论分析，研究舰船尾流的几何模型和气泡分布规律，提出了一种基于偏振特征的激光尾流探测方法。利用偏振光探测优势对探测器进出入气泡尾流的舷别信息进行分析，对所提出的方法进行了可行性实验研究。实验结果表明：偏振光探测装置可有效地分辨尾流区和非尾流区的散射光回波信号；当激光通过不同尺度、不同密度气泡区域时，探测器接收到的回波信号亦不同，且信号特征有规律可循。该方法能初步对尾流的舷别信息进行甄别，为尾流自导鱼雷探测舰船尾流从而进行目标跟踪提供了依据。

Abstract: The polarization characteristics of laser after scattering from bubbles and seawater are theoretically analyzed, and the geometric model of ship wake and the distribution law of bubbles are studied. A laser detection method for ship wake based on polarization characteristic is proposed. The allo-informations of bubbles and ship wake are analyzed, and the feasibility experiment of the proposed detection method is conducted. Experimental results show that the polarization detection device can effectively detect the scattered echo signals from the ship wake region and non-wake region through the proposed detection method. When the laser passes through the different-scale and density bubble regions, the detectors receive the different echo signals. This shows that the proposed detection method can be used for identifying the allo-information of ship wake.Key
