A novel 3-D reconstruction approach based on group sparsity of array InSAR [PDF]

Scientia Sinica Informationis, 2018
As an advanced technology, synthetic aperture radar tomography (Tomo SAR) provides the feasibility to solve the layover problem caused by the inherent side-view mode in SAR sensors. However, the conventional nonparametric spectral estimation methods, such as truncated singular value decomposition (TSVD), are limited by the poor elevation resolution and
