Tracing and Laser Detecting Ship Wake Based on Depolarization Effect
摘要
Abstract
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.关键词
