Calibration of COSMO-SkyMed SAR data for hydrology applications

In this paper we present a procedure for the calibration of SAR data devoted to extract physical information from Cosmo-Skymed images. The main purpose is the extraction of land cover indexes for hydrology applications. The calibration procedure was implemented in a rural context in Burkina Faso, where along with the technical challenges we faced socio-economic problems. A set of handmade trihedral corner reflectors were deployed and their response measured from SAR images. The results were used for calibration of an erosion product.
