Abstract

Abstract

A simulation model for the radar backscattering cross-section(σ⁰) of the sea surface has been developed based on the synthetic aperture radar(SAR) imaging mechanism of sea bottom topography.The relationship between topographic parameters and SAR mapping of sea bottom topography has been analyzed using the results of the simulation model.It is shown that water depth measured by SAR increases with increase of the height of the bottom topography.The bigger the slope of topography is,the easier it can be observed by SAR.SAR mapping of sea bottom topography also depends on the direction of the topography.The optimal direction of topography is the direction parallel to the flight direction of satellite while the perpendicular direction is the worst.
