Abstract

Based on the analytical expression derived from the high frequency ocean spectrum balance equation but not surface wave action balance equation, continuity equation and the first order Bragg backscattering theory, a simulating model for the shallow water bathymetry SAR relative normalized radar backscattering cross-section has been developed. The relationship between SAR relative normalized radar backscattering cross-section and currents, winds, wave length, incidence angle and the polarization has been simulated and the optimal conditions for shallow water bathymetry by SAR was also analyzed, the conclusion was given in the last section. Valuable help for the study on SAR shallow water bathymetry surveys will be provided from this paper.
