TomoSAR Mapping of 3D Forest Structure: Contributions of L-Band Configurations
Synthetic Aperture Radar (SAR) measurements are unique for mapping forest 3D structure and its changes in time. Tomographic SAR (TomoSAR) configurations exploit this potential by reconstructing the 3D radar reflectivity.

Building façades reconstruction using multi-view tomosar point clouds
Rich scatterer information retrieved by very high resolution SAR tomography using multiple data stacks from different viewing angles enables us to generate 4D point clouds of the illuminated area from space. They can be potentially used for facade reconstruction and deformation monitoring in urban environment.

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

Reconstruction of individual trees from multi-aspect TomoSAR data
AbstractThe localization and reconstruction of individual trees as well as the extraction of their geometrical parameters is an important field of research in both forestry and remote sensing. While the current state-of-the-art mostly focuses on the exploitation of optical imagery and airborne LiDAR data, modern SAR sensors have not yet met the ...
