Title:
Geodetic SAR tomography 
Abstract:
In this paper, we propose a framework referred to as ?geodetic SAR Tomography ?that fuses the SAR imaging geodesy and TomoSAR approaches to obtain absolute 3D positions of a large amount of natural scatterers. The methodology is applied on four very high resolution (VHR) 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 3D positions are retrieved by means of stereo-SAR, the point clou...    »
