摘要
基于偏振效应光尾流探测方法是利用偏振激光对含不同尺度气泡尾流及其与海水介质散射后的偏振差异来实现对尾流的有效检测和跟踪。在分析尾流几何模型及其气泡分布的规律的基础上,建立了舰船尾流偏振光检测模型,提出了一种偏振激光尾流检测方法,并利用偏振光特点对探测器进出入远、近距离尾流的舷别信息进行了分析,对此方法进行了可行性试验研究。试验结果表明:该方法可行,特别是能精确对远距离尾流进行探测,对远、近距离尾流都适用。
The principle of detection method for ship wake flow based on polarized laser is to efficiently detect and track ship wake flow through detecting scale bubble wake flow and its polarization difference after seawater medium scattering.On basis of analyzing ship wake flow geometric model and the distribution law of bubbles,build ship wake flow polarized laser detection model,a method for ship wake flow detection by polarized laser is proposed,and analyze long distance and short distance wake flow allo-information use polarized light characters,experimental research on feasibility of this method is carried out.Experimental results show that the method is feasible and it is suitable for both long distance and short distance ship wake flow,especially for long diatance ship wake flow detection.
