InSAR Elevation Inversion Method Based on Backprojection Model with External DEM

open access: yesLeida xuebao, 2021
When Interferometric Synthetic Aperture Radar (InSAR) is used to obtain the Digital Elevation Model (DEM), highly sloped terrains will make interferometric fringes dense and increase the difficulty of phase unwrapping, which will affect the accuracy of ...
