摘要
针对海浪破碎现象伴随的白冠和劈尖式卷浪结构会共同对激光散射特性造成显著影响,干扰探测和通信系统的问题,开展了破碎海面的光学散射特性研究。提出了一种基于流体力学与海洋粒子统计分布特性的三维破碎海面激光近程散射特性计算方法,并基于三维体网格剖分的蒙特卡罗方法计算破碎海面激光散射特性。仿真结果表明:该方法耦合了海面散射和海洋粒子散射的共同影响,能更准确地反映高海情下的光辐射传输特性。
Aiming at the problem of the white crown and wedge-shaped curling structure accompanying the breaking of sea waves,which will jointly cause a significant impact on the laser scattering characteristics and interfere with the detection and communication systems,research on the optical scattering characteristics of the broken sea surface has been carried out.A method for calculating the laser short-range scattering characteristics of three-dimensional broken sea surface based on fluid mechanics and the statistical distribution characteristics of ocean particles is proposed,and the Monte Carlo method based on three-dimensional volume meshing is used to calculate the laser scattering characteristics of the broken sea surface.The simulation results show that the method couples the combied effects of sea surface scattering and ocean particle scattering,and can more accurately reflect the optical radiation transmission characteristcs in extreme sea conditions.
