We present a two-dimensional theory of thermal emission and light scattering from an anisotropic wind-roughened water surface that is described by the Gaussian-Joint North Sea Wave Project model. The theory is developed through the use of the first-order geometrical-optics approxmation modified with shadowing effects, and it is valid when the average slopes of the surface are smaller than unity. The theory allows us to evaluate the effective emissivity and the effective bistatic reflectivity of a full-gravity-capillary wave surface at large viewing angles, for any direction relative to the average propagation direction of the surface wave. We also present an application of the theory to the recently proposed method for obtaining thermal imagery of a wind-roughened water surface from low altitudes, which is called statistically corrected ocean thermography. Corrected thermal images of the ocean surface, obtained by our field experiment, are shown.
我们提出了一种关于各向异性风蚀水面热发射和光散射的二维理论,该水面由高斯联合北海波浪项目模型描述。该理论是通过使用考虑阴影效应修正的一阶几何光学近似发展而来的,当表面平均斜率小于1时有效。该理论使我们能够评估全重力-毛细波表面在大视角下相对于表面波平均传播方向的任何方向的有效发射率和有效双站反射率。我们还将该理论应用于最近提出的从低空获取风蚀水面热图像的方法,即统计校正海洋热成像。展示了通过我们的现场实验获得的经校正的海洋表面热图像。
