Analysis of the spectral spaces of reflectance from crop canopies.

摘要

This paper reviews the different representations of the spectral spaces, mainly the visible spectrum and near infrared spectrum of the foliar reflectance of crops. The impacts of leaf area index, angular leaf distribution and leaf spectrum, and of the illumination-sensor geometry on the foliar reflectance patterns are discussed. The invariance properties of the solution for photon transfer processes in crop foliage, and a method for modelling crop growth stage are also discussed..
