Geodetic TomoSAR - Fusion of SAR imaging geodesy and TomoSAR for 3D absolute scatterer positioning. [PDF]
2014 IEEE Geoscience and Remote Sensing Symposium, 2014 In this paper, we propose a framework referred to as “geodetic TomoSAR“ that fuses the SAR image geodesy and TomoSAR approaches to obtain absolute 3D positions of a large amount of natural scatterers. The methodology is applied on four Very High Resolution (VHR) TerraSAR-X spotlight image stacks acquired over the city of Berlin.

Journal of Sensors, Volume 2021, Issue 1, 2021., 2021 Downward‐looking linear array synthetic aperture radar (DLLA SAR) is a kind of three‐dimensional (3‐D) radar imaging system. To obtain the superresolution along the crosstrack direction of DLLA SAR, the sparse regularization models with single measurement vector (SMV) have been widely applied. However, the robustness of the sparse regularization models

Statistical Regularization for TomoSAR Imaging With Multiple Polarimetric Observations [PDF]
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 The polarimetric versions of focusing techniques for synthetic aperture radar (SAR) tomography (TomoSAR), apart from estimating the pseudopower and retrieving the height of reflectors from the recovered local maxima, allow extracting the associated scattering mechanisms.

Evaluating P-Band TomoSAR for Biomass Retrieval in Boreal Forest [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2021 P-band synthetic aperture radar (SAR) is sensitive to above-ground biomass (AGB) but retrieval accuracy has been shown to deteriorate in topographic areas. In boreal forest, the signal penetrates through the canopy to interact with the ground producing variations in backscatter depending on ground topography, forest structure, and soil moisture ...
