Abstract

The aim of this paper is to evaluate Synthetic Aperture Radar (SAR) capability to estimate the wind vector and two dimensional wave spectra, in the coastal waters off Gujarat, India. In the present study directional wave spectrum has been estimated using the quasi-linear method. The resulting ocean wave spectrum has been compared with the in-situ buoy data and ocean wave model-derived spectrum. The results show a good match between them. An attempt has also been made to determine wind speed and direction information for the same region using CMOD4 algorithm and the results have been compared with the QuikSCAT derived winds. It was also found that SAR is able to provide finer features and up to very near to the coastal region in comparison to the Scatterometer winds.
