A Detection Method for Ship Wake Based on Polarization Characteristic

TIAN Jing;BAI Guang-fu;JIANG Yang;School of Physics,Guizhou University;  
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.
