The nonLambertian Problem in the Dynamic Minitoring of Vegetation by NOAAAVHRR
At present NOAAAVHRR can offer us many multiangle earth observation data.through careful collection of successive AVHRR images
the existence of nonLambertian effect had been proven. Its relative variance will not be larger than 30%. It is not surprising large
but it can not be neglected too. This paper reports an initial study about how to correct the nonLambertian effect through building up BRDF models for vegetation and soil background and with the help of decomposing method of mixed pixel.Results show our method is basically correct and practical. Further study is still needed because of the effect of nonLambertian mixed with other problems
