Inverse Synthetic Aperture Radar Sparse Imaging Exploiting the Group Dictionary Learning

Remote Sensing, 2021
Sparse imaging relies on sparse representations of the target scenes to be imaged. Predefined dictionaries have long been used to transform radar target scenes into sparse domains, but the performance is limited by the artificially designed or existing ...
