Title:
Geodetic SAR Tomography
Abstract:
In this paper, we propose a framework referred to as “geodetic synthetic aperture radar (SAR) tomography” that fuses the SAR imaging geodesy and tomographic {SAR} inversion ({TomoSAR}) approaches to obtain absolute 3-D positions of a large amount of natural scatterers. The methodology is applied on four very high resolution {TerraSAR}-X spotlight image stacks acquired over the city of Berlin. Since all the {TomoSAR} estimates are relative to the same reference point object whose absolute 3-D pos...    »
