A new directional brightness temperature model suits to the polymorphism canopy within the whole growth circle

摘要

We propose a new model to calculate the Directional Brightness Temperature (DBT) over the canopy of the row-planted corn. The most advantage of this new model is to simulate the DBT over the canopy cross the whole growth circle, both row structured and homogeneous structured. As the geometric structure of canopy changes greatly while the biomass grows from sparse to continuous, this new model is a better option as a tool to analysis remote sensing data.
