Abstract

A new remote sensing technique based on the analysis of Synthetic Aperture Radar (SAR) images of waves has been developed for estimation of near-shore coastal water bathymetry. Near-shore coastal water regions generate a rich range of surface signatures observable by SAR, mainly due to effects of spatially changing water depths that cause variations in the ocean surface roughness. These signatures contain a great deal of information regarding wave's parameters and their variation over the area including the wavelength of surface waves change over varying water depths. By approaching the analysis of SAR images of waves, using images analysis techniques and the general desperation relation of ocean waves, new indirect technique of remote sensing bathymetry is applied over near-shore coastal water regions in Wenzhou Zhejiang province, China. Results show that this technique is especially suitable for the near-shore coastal water zone where the water depths change.
