Abstract

A complete polarimetric study on C-band RADARSAT-2 data over vineyards in Spain has been performed in order to explore the sensitivity to growth stages. This analysis suggests that scattering response of vines can be approximated as a two-component scenario comprising a strong return from soil and a weak depolarized return due to grapes and leaves. A Water Cloud Model parameterization of the cross-polar intensity is proposed as a function of the development of grapes and LAI changes over time.
