Analysis and retrieval of soil parameters with specular scattering data at different incidence angle

Abstract

In this paper, we have analyzed the angular response of specular scattering coefficient for different soil texture fields while varying soil moisture and surface roughness at C-band. An approach based on multi-incidence angle data has been developed to retrieve soil texture, soil moisture and surface roughness. An empirical relationship has been developed between normalized specular scattering coefficient and surface roughness parameters. This empirical relationship has been utilized along with the Kirchhoff Scalar Approximation to retrieve soil texture, soil moisture and surface roughness. Obtained results are in good agreement with ground truth data. © 2013 IEEE.
