A TomoSAR regularization-based method for height change detection in urban areas
International Journal of Applied Earth Observations and GeoinformationOver the past years, urban change detection has always been a challenging issue for researchers. Due to the two-dimensional intrinsic property of satellite imageries and the inherent less intuitive interpretability of radar images, height change ...

Deep SAR Tomography: A Model-Inspired Approach With Learned Sparse Regularizer
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSynthetic aperture radar tomography (TomoSAR) can acquire high resolution in height direction by forming a large synthetic aperture along the tomographic direction. Compressed sensing (CS) is widely utilized in TomoSAR imaging to reduce the costs of data

Façade structure reconstruction using spaceborne TomoSAR point clouds.
, 2012 Very high resolution SAR tomography using multiple data stacks from different viewing angles enables us for the first time to generate 4D point clouds of the illuminated area from space with a point density comparable to LiDAR. They can be potentially used for façade reconstruction and monitoring in urban environment.

A Single-Pass Multistatic SAR Satellites Formation Design Method for TomoSAR Data Acquisition
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSynthetic aperture radar tomography (TomoSAR) enables 3-D SAR imaging. However, most spaceborne TomoSAR data are currently acquired through repeated passes of a single satellite, during which the atmospheric and deformation phases complicate processing ...
