A Dual-baseline Polarimetric SAR Interferometry Method for Building Height Inversion

  • In the building height inversion of urban area, as the phase center of different scatterers within a resolution cell will cause the ambiguity in the interferometric phase, compromising the accuracy of building height inversion To solve this problem, this paper proposes a dual-baseline PolInSAR building height inversion method. We use dual-baseline PolInSAR data to addobservations. Then, we use optimal criteria for removing the phase ambiguity within a resolution cell. To validate the proposed method, we selected three sets of high-resolution TerraSAR-X data covering Tai'an City, Shandong for experiments and compared the experimental results with ground truth data. The inversion accuracy of the proposed method was improved over the results obtained from the traditional single baseline method.
