Preliminary model for wind estimation from Cosmo/SkyMed X band SAR data

In the paper we present a preliminary model for wind estimation from SAR data in X band. The data set we have used is composed of more than 300 Cosmo/SkyMed SAR images and the wind data obtained from the SeaWinds instrument on QuikSCAT. We have derived 18 parameters to express σ_o as function of wind intensity, direction and Radar look angle. The preliminary validation results are encouraging although our data set needs to be extended in order to increase those conditions poorly represented.
