Evaluation of a rough soil surface description with ASAR-ENVISAT radar data
چکیده انگلیسی
Two presentations of the surface height correlation function are proposed in this study. The first one, referred to as the “α function” fits the experimental correlation functions up to the correlation length, while the second one, the “(a,b) function”, fits the correlation function for scales corresponding to positive values. A relationship is proposed between the rms height of soil surface and the shape of the correlation function. Using the α function, comparisons between radar measurements for high incidence angles and simulations based on the numerical backscattering model (moment method) show a good agreement for soil surfaces with an rms height smaller than 2 cm with medium and high soil moisture.
