Radar Image Processing



This research investigates methods to improve the clarity of radar generated images.




The concept that images could be generated from radar signals has been around for years.  However, only recent advancements in computer processing power have allowed for these theories to be tested.  Radar imaging has many applications and is just in its early stages of development.  It is currently being applied to map objects in 3-D and to see through walls.  These applications of radar imaging tend to experience interference and research is being done to improve image clarity.
