摘　　要：通过测量空间辐射反演海雾气溶胶的微观特性是一种重要的遥感方法,但是海雾对辐射的反射会受到海面背景的影响。该工作研究了海雾与海面的耦合多次散射。利用Mie理论研究了海雾气溶胶的单次散射特性,利用辐射传输理论研究太阳光在无下垫面海雾中传输多次散射特性;在基尔霍夫近似下研究了风驱粗糙海面的散射特性,并考虑了海面的遮蔽效应,得到了风驱海面随风速的反射函数。根据累加法研究了海雾和海面的耦合散射,计算结果表明海雾在有粗糙海面作为背景的情况下,其整体反射有较大增强。The present paper is concerned with computing the multiple scattering characteristics of a sea fog-sea surface couple system within this context.The single scattering characteristics of sea fog were studied by Mie theory,and the multiple scattering of sunlight by single sea fog layer was studied by radiative transfer theory.The reflection function of a statistically rough ocean surface was obtained using the standard Kirchhoff formulation,with shadowing effects taken into account.The reflection properties of the combined sea fog and ocean surface were obtained employing the adding method,and the results indicated that the reflected light intensity of sea fog increased with the sea background.
