A Two-Step Dual-Polarimetric Sparse Bayesian Learning D-TomoSAR Method for Urban Building Deformation Monitoring
SAR tomography (TomoSAR) is capable of separating scatterers at different elevations within the same range–azimuth resolution cell. Differential TomoSAR (D-TomoSAR) further incorporates temporal information, enabling joint estimation of scatterer elevation and deformation velocity. Most existing sparse inversion method...
