摘要

The test device (12) has a reflector unit (18) for reflecting the radar beams, which is mounted on a carrier vehicle (10) moving in the front of a motor vehicle and pivoted around vertical axis. A boom (14) is pivotally held at a holding unit (16) that is fastened to a carrier vehicle side. The reflector unit has two corner reflectors (20), which are offset to each other in the vertical direction or in the transverse direction of the boom. The boom and the support vehicle are provided with a radar beam scattering or absorbing surface.
