Abstract
Wind speed and direction are estimated from backscatter σ° measurements at two adjacent sub-scenes of RADARSAT-1 synthetic aperture radar (SAR) images, each sub-scene with slightly different incidence angles. Resultant wind vectors are validated using in-situ buoy measurements, and compared with SAR-derived wind vectors obtained by using the wind directions determined from a spectral analysis of SAR images and co-located QuikSCAT measurements, as inputs to a hybrid model wind retrieval model. The implemented hybrid model consists CMOD-IFR2 (applicable to C-band, VV polarization) and the C-band co-polarization ratio for Kirchhoff scattering. The new algorithm displays improved skill in wind vector estimation from RADARSAT-1 SAR data.
