Harding, Brian J.; Milla, Marco
(Instituto Geofísico del Perú, 2013-10)
A novel technique for radar-imaging inversions is proposed which leverages ideas from the emerging field of compressed sensing. This new method takes advantage of the transform sparsity inherent in natural images. Theoretical ...
