Abstract :
The physical microwave vegetation radiometry model developed at Aerojet is employed to investigate the impacts of environmental conditions on microwave radiometry of vegetation/forest. The model is based on solution of the radiative transfer equations and it operates over a wide frequency band in the microwave and millimeter wave regions for both coniferous and deciduous forest as well as grass and agriculture crops. Numerical simulations based on the model showed that the horizontally polarized temperature is more sensitive to the seasonal variations than the vertically polarized temperature
