摘要: Traditional Synthetic Aperture Radar (SAR) imaging theory of underwater topography is explained by flow field model, wave model and radar backscatter model. However, the models are simplified there still many uncertain problems to be studied. In order study large scale abrupt SAR, a nonlinear introduced. This helpful obtain details sea surface modulated topographic waves. The hybridizable discontinuous Galerkin (HDG) used solve compressible Navier-Stokes (NS) equation interaction between field. calculation results taken into action spectrum balance, then backscattering coefficient calculated based on Bragg scattering. Finally, imaged BP algorithm. show that SAR image fringe with corresponds topography, linear not obvious.
