利用不同尺度气泡与海水介质对激光散射后退偏状态的差异性进行尾流检测并实现尾流寻迹。仿效声尾流导引的模式，通过尾流中不同密度、尺寸气泡群与海水水体的分辨达到对尾流边缘区域的识别。试验结果表明，本文的方法能够有层次地分辨不同密度、尺度气泡散射体和海水介质的回波信号，并反映出气泡密度对散射光退偏效应的敏感性。试验结果具有一定的规律性，表明该方法可以实现探测器对进出尾流的甄别。

The purpose of this paper is to find a method for accurately detecting and tracing ship wake by making use of the difference of depolarization states due to laser scattering of bubbles with different scale and seawater. Imitating acoustic wake guidance mode, ship wake edge region is recognized through identification of the bubbles with different density and scale from sea water. Experiment results show that this method clearly distinguishes these echo signals, and displays the sensitiveness of bubble density to depolarization effect of scattered light. These results show certain regu-larity, which infers that this method can be used to accurately and clearly distinguish ship wake.
