Abstract :
This study is a preliminary research to extract the oceanic information such as ocean wind and wave using SAR images. The CMOD4, CMOD-IFR2, and polarization ratio (PR) models are used to estimate the magnitude of wind and the SAR-wave spectrum analysis and inter-look cross-spectra methods provides the wave information related to amplitude and direction of the ocean wave over a square-km sized area.
