Abstract :
This paper presents an overview of the results obtained on Montespertoli area, Florence, Italy, from different SAR missions. An analysis of the sensitivity of radar backscattering to some parameters which are of primary importance in modelling the geophysical processes of the hydrological cycle has been carried out. In particular the effects of surface roughness and soil moisture on microwave backscattering have been investigated
