中文摘要：

水面溢油是最常见的水体污染源之一,在反射、散射和透射电磁辐射的过程中,将表现与它们自身性质有关的偏振特性.因此,对水面溢油的多角度偏振信息探测成为水体定量遥感的一种新手段.偏振反射是伴随目标的二向性反射而产生的,在探测目标地物的二向性反射的同时,可以通过起偏器获得目标地物偏振态的三维空间分布.本文从多角度偏振遥感机理的角度出发,研究了水面溢油的多角度偏振反射与二向性反射之间存在的定量关系,并从实验上验证了其二向性反射、45°偏振、偏振均值三者在2π空间的相应方位角、天顶角、探测角以及通道上的反射比均相等.

英文摘要：

Water-surface Oil Spill is one of the most popular pollution of water, In the process of reflecting, scattering and transmiting electromagnetic wave, it can produce polarized characteristics which are related to the nature themselves ; therefore, detecting Water-surface Oil Spill＇ multi-angle polarization information becomes a new method of quantitative remote sensing. For polarized reflectance always goes with bidirectional reflectance, we can attain the polarized three-dimensional spatial distribution of the targets by a polarimeter when detecting its bidirectional reflectance. From the point of view of multi-angle polarized remote sensing mechanism, this paper studied the quantitative relation between polarized BRDF and BRDF of Water-surface Oil Spill, and from the experimentations testified its equality of the reflectance of bidirectional reflect, polarized reflect of 45 degree and polarized reflect of mean value in the corresponding azimuth angle, zenith angle, detection angle and detection channels in 2π space.
