"The signal processor is that part of the system which separates targets from clutter on the basis of Doppler content and amplitude characteristics. Information theory plays critical and unique roles in facilitating and enabling many radar signal processing problems. In addition, in the last decade, we have witnessed a significant increase in the use of information theory for radar signal processing, partially due to increased civilian applications of radar systems, such as automotive radar and radars for gesture recognition, that made the results to be more easily disseminated than the military counterparts which have dominated radar system development in the previous several decades."-- Provided by publisher.
