AN ULTRA-WIDEBAND RADAR IMAGING SYSTEM USING A TWO-DIMENSIONAL MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) TRANSDUCER ARRAY

摘要

A radar transducer array (12) for an ultra-wideband imaging radar system (10) operating at a reference wavelength ?c comprises transmission antenna elements (14) or reception antenna elements and reception antenna elements (16), which are located at specific locations of the array plane in such a way that high image quality is achieved with a minimum number of antenna elements (14, 16), resulting in less complex hardware as well as significantly reduced computational effort.
