ANALYSIS OF BATHYMETRIC FEATURES USING SAR IMAGE: AN EXAMPLE FROM THE SOUTHERN NORTH SEA

This paper presents the authors' simulation model of the bathymetric features on SAR image and their inversion model for detecting bathymetric features by SAR image. A function G proportional to the radar backscatter cross section σ^sub 0^ is defined to simulate the radar image gray tone level...

Summary:This paper presents the authors' simulation model of the bathymetric features on SAR image and their inversion model for detecting bathymetric features by SAR image. A function G proportional to the radar backscatter cross section σ^sub 0^ is defined to simulate the radar image gray tone level based on Yuan (1997). The inversion method is the minimum deviation solution proposed by Jin and Yuan (1997b). Tests with actual data of the Seasat SAR image and the sea chart of the southern North Sea showed that the models could simulate and detect the basic bathymetric features.[PUBLICATION ABSTRACT]
