Abstract
A system for testing vehicular radar is described. The system include a diffractive optical element (DOE) configured to diffract electromagnetic waves incident on a first side from a radar device under test (DUT). The system also includes a re-illumination element adapted to receive the electromagnetic waves diffracted from the DOE from a second side. The re-illumination element being adapted to transmit apparent angle of arrival (AoA) electromagnetic waves back to the DOE.
