A method to detect wind direction of ocean surface by using shallow water topography and its SAR image

SAR images include information of wind field of ocean surface.A new method in which the maximum correlation coefficient method was used to determine the wind direction of ocean surface was presented.This method uses shallow water topography,its SAR image and its simulation SAR image which was obtained by using the shallow water topography SAR image simulation model.The ocean area of Shuangzi Reefs in the Nansha Islands was taken as an example and the wind direction of ocean surface was analyzed by using one scene RADARSAT SAR image.The results show that the method which is used in wind direction detection with the SAR images of shallow water topography is practicable.
