Abstract
A system for testing vehicular radar is described. The system include a free-space polarization adapter (FSPA) configured to alter a first polarization state of electromagnetic waves from a radar device under test (DUT) to a second polarization state, which is different than the first polarization state; and a re-illuminator adapted to receive the electromagnetic waves having the second polarization state from the FSPA.
