 This study uses Chinese Gaofeng III synthetic aperture radar, SAR, images collected under typhoon conditions to retrieve sea surface waves, with a criterion of 0.15 m root mean square error, IMSE, for the significant wave height, SWH. The proposed algorithm outperforms empirical approaches developed for retrieving SWH using GF-3 SAR imagery in GLO and WSC imaging modes.
