Abstract
ONE OF THE ISSUES WHICH CONTINUE TO CONCERN PLANNERS AND THE DESIGNERS OF FUTURE RADAR SYSTEMS IS THE SIDELOBES OF THE DISTRIBUTED SPARSE ARRAY RADAR (DSAR). AS A GENERAL RULE, PERFORMANCE IN BOTH CLUTTER AND JAMMING TENDS TO DEGRADE AS SIDELOBE LEVELS INCREASE. FURTHERMORE, IN ORDER TO MAKE USE OF THE HIGH RESOLUTION POTENTIAL OF DSAR FOR IMAGING, RAID COUNT, OR VERY ACCURATE TARGET LOCATION, THE ARRAY SIDELOBES MUST BE CONTROLLED. THE TECHNICAL OBJECTIVE OF THE PHASE I EFFORT IS TO DEFINE AND ANALYZE INNOVATIVE APPROACHES FOR THE REDUCTION OF DSAR SIDELOBES AND FOR SUPPRESSING CLUTTER RETURNS WHICH ARISE FROM THE RESIDUAL SIDELOBES. TECHNIQUES SUCH AS OPTIMAL SPACE-TIME PROCESSING, MAXIMUM LIKELIHOOD PROCESSING AND CLEAN ALGORITHMS WILL BE EVALUATED.
