Abstract

Wind wind stress and drag coefficient of ocean surface are very important parameters in the studies of ocean and atmospheric dynamics especially in that of air-sea interaction. It is shown in this paper that wind wind stress and drag coefficient of ocean surface can be measured remotely with high resolution by synthetic aperture radar (SAR). A model has been developed based on SAR imaging mechanisms of ocean surface capillary waves and short gravity waves. A Radarsat SAR image of coastal ocean of south of Hainan Island has been used to calculate wind stress and drag coefficient. Good results have been achieved.
