Statistical Regularization for Enhanced TomoSAR Imaging [PDF]
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 One of the main topics in synthetic aperture radar (SAR) tomography (TomoSAR) is the estimation of the vertical structures' location, which scatter the field back toward the sensor, constrained to a reduced number of passes. Moreover, the introduction of artifacts and the increase in the ambiguity levels due to irregular sampling, consequence of ...
