Test bench for testing a distance sensor operating with electromagnetic waves

A test bench (1) is described and shown for testing a distance sensor (2) operating with electromagnetic waves, wherein the distance sensor (2) to be tested comprises at least one sensor radiating element (3a) for radiating a transmission signal (4) and a sensor receiving element (3b) for receiving a reflection signal, with a receptacle (5) for holding the distance sensor (2) to be tested, with an at least partially movable connecting member (6, 6m, 6s) in the radiation area of a distance sensor (2) held in the receptacle (5), with at least one test bench receiving element (7) held in the connecting member (6, 6m, 6s) for receiving a transmission signal (4) radiated by the sensor radiating element (3a), and with at least one test bench radiating element (8) held in the connecting member (6) for radiating a test bench transmitting signal (9) as a simulated reflection signal.A reliable environment simulation, in particular for the testing of multiple input-multiple output distance sensors (2) is achieved in that at least one test bench receiving element (7, 7a, 7b) and one test bench radiating element (8, 8a, 8b) are arranged together in a movable part (6m) of the connecting member (6).
