Abstract: 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.

Abstract: A method for calibrating a target simulator for an active environment detection system includes: calibrating a complete signal path comprising a first signal path and a second signal path by determining a first deviation of a first value of at least one signal parameter from a first reference value of the at least one signal parameter; calibrating one of the first signal path and the second signal path by determining a second deviation of a second value of the at least one signal parameter from a second reference value of the at least one signal parameter; and calibrating the other of the first signal path and the second signal path by offsetting of the first deviation with the second deviation.
