摘要
针对二向性造成的辐射失真 ,在核驱动模型的基础上提出了一种改进的二向性反射分布模型 ,并通过对MODIS影像的试验 ,得到了减弱辐射差异的较好效果 。
Bi-directional reflectance characteristic is one of the most important factors of radiance distortion. This paper discusses the radiance distortion caused by ground bi-directional reflectance character and puts forward an improved bi-directional reflectance distribution function (BRDF) model based on kernel-driven model. The experiment of MODIS radiometric calibration shows that the improved approach is effective for MODIS radiance distortion.
