摘要
在船舶海上航行的过程中,与运动方向相反的方向会形成尾迹,也被称为船舶尾流。由于螺旋桨与海水的相对运动,船舶自身会受到较强的冲击,从而产生局部的高温,进而形成气泡幕带,存在诸多物理性质。在水温、天气、航速、气温以及海域等诸多因素的影响下,尾流的物理与外貌特征也逐渐突显出来。需要注意的是,船舶尾流的组成部分是海水当中处于运动状态的气泡,其对尾流气泡散射特性产生了直接影响。而偏振特性同样具有散射光的特征,不仅能够提供光强信息,同样也涵盖了其他价值较高的信息。基于此,文章将远程尾流散射光偏振特性作为主要研究内容,并重点阐述蒙特卡罗模拟的实现过程。
In the course of a ship’s maritime navigation,a trail is formed in the opposite direction of the direction of motion,also known as the wake of the ship.Due to the relative motion of the propeller and the seawater,the ship itself will be subjected to a strong impact,resulting in local high temperatures,which in turn form a bubble curtain,and there are many physical properties.In the influence of water temperature,weather,speed,temperature and sea area,the physical and external features of the wake are gradually highlighted.It should be noted that the components of the ship’s wake are the moving bubbles in the sea,which have a direct impact on the wake scattering characteristics of the wake.The polarization characteristics also have the characteristics of scattered light,which not only provides light intensity information,but also covers other high-value information.Based on this,the paper takes the polarization characteristics of remote wake-scattered light as the main research content,and focuses on the implementation process of Monte Carlo simulation.
