Abstract

A new method for retrieving significant wave height (SWH) directly from synthetic aperture radar (SAR) imagery without prior knowledge of ocean wave spectra is presented. It is based on the azimuthal high-wavenumber cutoff effect and the empirical relationship between mean period and peak period of ocean waves. Envisat ASAR wave mode data are used in case studies. Comparison shows that the retrieved SWHs are in good agreement with data from GFO, TOPEX/Poseidon altimetry and ECMWF.
