Abstract

A system for measuring the transfer function on a path from a feed antenna via a reflector to a radar sensor testing zone includes: an anechoic chamber; the feed antenna, wherein the feed antenna is configured to transmit and receive a radar signal, and wherein the feed antenna is disposed, together with the reflector, within the anechoic chamber; the radar sensor testing zone, wherein the radar sensor testing zone is a predetermined area within the anechoic chamber; and a retroreflector disposed in the radar sensor testing zone, wherein the retroreflector is configured to cause at least a portion of a measurement signal in the radar frequency range to be reflected back to the feed antenna via the reflector, wherein the measurement signal is received from the feed antenna via the reflector.
