Although the field of sparse representations is relatively new, research activities in academic and
industrial research labs are already producing encouraging results. The sparse signal or parameter
model motivated several researchers and practitioners to explore high complexity/wide bandwidth
applications such as Digital TV, MRI processing, and certain defense applications. The potential
signal processing advancements in this area may influence radar technologies. This book presents
the basic mathematical concepts along with a number of usefulMATLAB® examples to emphasize
the practical implementations both inside and outside the radar field.
