A Comparison of Tomographic SAR Reconstruction Methods Using Spaceborne Data

The main objective of the paper is to give a review and comparison of the reconstruction techniques in SAR tomography. The algorithms are compared with a real dataset obtained from TerraSAR-X. The paper explains the building of Tomographic data for high resolution (HS) Spotlight mode. Further, a comparitive analysis of MUSIC and Compressive sensing (CS) based Sl1mmer will be presented.
