The Facilitation of SRTM DEM-Derived Interferogram to Accurate DEM Reconstruction

摘要：

A novel approach is proposed in this paper to exploit the Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) to improve the accuracy of digital elevation model (DEM) reconstruction in interferometric synthetic aperture Radar (InSAR). The proposed algorithm can be applied to facilitate the DEM reconstruction problem. i.e, the raw and simulated interferograms can be fused by introducing a userdefined weighting factor, that is, in regions of higher coherence, the raw interferogram with the interferometry method are remained, and in regions of lower coherence, the interferogram is updated with the simulated one. Some experimental results with ERS data verify the theoretical analysis and show that the method can improve the performance of the DEM reconstruction to a great extent.
