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

Test bench for testing a distance sensor operating with electromagnetic waves

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.
