Abstract: Wide-swath synthetic aperture radar (SAR) observes the large-scale ocean surface field. With SAR instruments, we can actively monitor phenomena in the coastal ocean and marine atmospheric boundary layer at very high spatial resolution (on the order of tens of meters) in all weather conditions day and night. SAR observations are particularly useful in coastal regions where clouds are usually present, causing observation problems for visible and infrared sensors. Spaceborne SAR can provide swath coverage of about 450 km, wide enough to cover many oceanic and atmospheric meso-scale features. In this presentation, The SAR observations of oceanic surface signatures associated with winds, surface waves, internal waves, tidal convergence fronts, oil spills, bathymetry, and other oceanic features are discussed.
