SAR data analysis for wave spectrum, bathymetric, and coastal information

In this study, JERS-1 SAR data were examined and analyzed for extraction of coastal information, namely: (i) wave spectra, (ii) sea bottom topography, (iii) mangrove species classification, and (iv) mangrove forest biomass. The wave spectra were extracted using Fast Fourier Transform whilst, the...
