Urban Tomographic Imaging Using Polarimetric SAR Data

Remote Sensing, 2019
In this paper, we investigate the potential of polarimetric Synthetic Aperture Radar (SAR) tomography (Pol-TomoSAR) in urban applications. TomoSAR exploits the amplitude and phase of the received data and offers the possibility to resolve multiple ...

A Single-Pass Multistatic SAR Satellites Formation Design Method for TomoSAR Data Acquisition

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic 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 ...

A TomoSAR regularization-based method for height change detection in urban areas

International Journal of Applied Earth Observations and Geoinformation
Over 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 ...
