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.
