Sparse reconstruction applied to tomographic SAR inversion

Full text not available from this repository.


The highly anisotropic 3D resolution element of modern spaceborne multi-baseline SAR systems allow us to exploit sparsity for superresolution tomographic SAR inversion. This is particularly true for mapping of urban infrastructure. The proposed algorithm “SL1MMER” is shown to be efficient. Its superresolution power is derived by simulations and demonstrated with real TerraSAR-X data. 3D reconstructions of buildings are presented including their seasonal thermal deformations at resolution and coverage levels not possible so far.
