Abstract
Recent studies have demonstrated that Global Navigation Satellite System-Reflectometry (GNSS-R) can be used for global wind-speed measurements over the ocean. Delay-Doppler Maps (DDM) are produced continuously by CYGNSS observatories are currently used for wind speed retrievals either directly or after calculation of global observables. The work presented in this paper shows that fine results can be obtained using the scattered power function observable. Experiments are based on real DDMs collected by the space CYGNSS observatories and by ground truth data processed within the collaborative NASA CYGNSS science team.File in questo prodotto:
