COORDINATED MINI-RADAR TARGET SIMULATORS FOR IMPROVED ACCURACY AND IMPROVED GHOST CANCELLATION

Abstract:

A system for testing vehicular radar is disclosed. The system includes a re-illumination element adapted to receive electromagnetic waves, and to transmit response signals. The re-illumination element includes: a plurality of miniature radar target simulators (MRTS's), each comprising: a receive antenna; a variable gain amplifier (VGA); an in-phase-quadrature (IQ) mixer; a variable attenuator; and a transmit antenna. The MRTS's are disposed in an array comprising rows and columns of the MRTS's, and each MRTS of the array is laterally spaced a distance p.sub.x and vertically spaced a distance p.sub.y from an adjacent MRTS. An incremental subtended azimuth angle (.delta..PHI.) and an incremental subtended elevation (.delta..theta.) angle are finer than an azimuth resolution specification (.PHI..sub.res) and an elevation resolution specification (.theta..sub.res) of a radar device under test (DUT).
