A novel imaging approach for multi-baseline SAR tomography

MB-TomoSAR (multi-baseline SAR tomography) is the most promising technique to realize the real 3-D (three-dimensional) resolution of the observed target zones in future. In this paper, the state art of MB-TomoSAR is briefly reviewed firstly. Secondly, a more general MB-TomoSAR model is described, and a novel imaging approach of processing MB-TomoSAR data is proposed base on this general model. Thirdly, the emphasis is placed onto the simulation of MB-TomoSAR, and the method has been proved able to process the MB-TomoSAR data. Finally, a conclusion is given, and the new challenges on MB-TomoSAR in application are discussed.
