A Novel Strategy for Radar Imaging Based on Compressive Sensing [PDF]

open access: yes, 2010
Radar data have already proven to be compressible with no significant losses for most of the applications in which it is used. In the framework of information theory, the compressibility of a signal implies that it can be decomposed onto a reduced set of
