We report on the retrieval of directional sea-roughness (the full directional mean square slope, including direction and isotropy) through inversion of Global Navigation Satellite System Reflections (GNSS-R) data collected during an experimental flight at 1 km altitude. The emphasis is on the utilization of the entire Delay-Doppler Map (DDM) in order to infer ocean roughness directional parameters. Obtained estimates are analyzed and compared to Jason-1 measurements and ECMWF numerical weather model outputs. We highlight the impact of long waves on scatterer velocity and the Delay Doppler spectrum. 1.
