Abstract

An L-band geophysical model function (GMF) is developed using Japanese Earth Resources Satellite-1 (JERS-1) SAR data. This GMF describes the relationship among L-band NRCS and ocean surface wind speed and direction. It enables us to convert JERS-1 SAR image into a wind-speed map. Using retrieved SAR wind, a high-resolution wave prediction model, SWAN (Simulating WAves Nearshore) was derived to demonstrate SAR high-resolutions winds.
