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...

Polarization-Optimized D-TomoSAR for Urban Building Monitoring With PAZ Data

Differential tomographic synthetic aperture radar (D-TomoSAR) has emerged as a powerful technique for 3-D reconstruction and deformation monitoring of urban buildings. However, most existing spaceborne SAR tomography studies have only used single-polarization channels, leaving the advantages of multipolarization inform...
