Abstract: A method and a radar target simulator for generating a simulated radar echo signal. A radar signal is sent with known bandwidth from a radar sensor to be tested. The radar signal is received in the radar target simulator. The radar signal is filtered via a low-pass filter with known filter curve. The frequency spectrum of the filtered radar signal over the full bandwidth of the low-pass filter is determined. A corrected frequency spectrum and the power of a radar signal corresponding to the corrected frequency spectrum are calculated. A scaled radar signal from the filtered radar signal and the radar echo signal as a reflection of the scaled radar signal are calculated. The radar echo signal is sent from a transmitting antenna of the radar target simulator to the radar sensor to be tested.

Abstract: A mechanical switching unit for selectively moving a functional component from a first position to a second position has an input element, an output element, a first holding point and a second holding point. The input element is set in motion by a drive. The output element is in engagement with the input element and is set in motion by the input element. The input element moves the output element from the first position to the second position, and vice versa. In the process, the functional component is moved from the first position to the second position, and vice versa. The first holding point exerts a first holding force on the functional component in the first position. The second holding point exerts a second holding force on the functional component in the second position.
