Abstract: A testing device for testing a distance sensor that operates using electromagnetic waves includes: a receiving element for receiving an electromagnetic free-space wave as a receive signal (SRX); and a radiating element for radiating an electromagnetic output signal (STX). In a test mode, a test signal unit generates a test signal (Stest), and the radiating element is configured to radiate the test signal (Stest) or a test signal (S′test) derived from the test signal (Stest) as the electromagnetic output signal (STX). In the test mode, an analysis unit is configured to analyze the receive signal (SRX) or the derived receive signal (S′RX) in terms of its phase angle (Phi) and/or amplitude (A) and store a determined value of phase angle (Phi) and/or amplitude (A) synchronously with the radiation of the test signal (Stest) or of the derived test signal (S′test) as the electromagnetic output signal (STX).

Abstract: A testing device for testing a distance sensor includes a receiving element for receiving an electromagnetic free-space wave as a receive signal, and a radiating element for radiating a simulated reflection signal. The receive signal or a signal derived therefrom is routed via a time delay circuit, and is thus time-delayed to a time-delayed signal. The time-delayed signal or a signal derived therefrom is radiated as the simulated reflection signal. The time delay circuit has an analog delay path and a digital delay path. The analog delay path implements shorter time delays than the digital delay path, apart from a possible overlap region. An input switch is used to switch the receive signal or the signal derived therefrom to the input of the analog delay path or to the input of the digital delay path, and the signal becomes the time-delayed signal after passing through the connected delay path.

Abstract: A method for testing a distance sensor includes: receiving an electromagnetic free-space wave as a receive signal; generating a simulated electromagnetic reflection signal therefrom; shifting a reflection frequency of the reflection signal by a Doppler frequency smaller than a signal bandwidth of the receive signal; converting the receive signal into a first work signal having a first work frequency smaller than a receive frequency of the receive signal; converting the first work signal into a second work signal having a second work frequency, wherein the difference between the first and second work frequencies is at least as large as the signal bandwidth plus the Doppler frequency; converting the second work signal into a third work signal having a third work frequency that corresponds to the first work frequency shifted by the Doppler frequency; increasing the third work signal by the conversion frequency; and radiating the third work signal.

Abstract: A testing device for testing a distance sensor includes: a receiver for receiving an electromagnetic free-space wave as a receive signal; an analog-to-digital converter configured to, in a simulation mode, convert the receive signal into a sampled signal; a signal-processing unit configured to: delay the sampled signal or a modulated sampled signal to form a delayed sampled signal or a modulated delayed sampled signal; and modulate, upon the sampled signal or upon the delayed sampled signal, a predeterminable Doppler signature as a characteristic motion profile of a reflecting object to be simulated to form the modulated sampled signal or the modulated delayed sample signal; a digital-to-analog converter configured to convert the modulated or the modulated delayed sampled signal into a simulated reflected signal; and a transmitter configured to radiate the simulated reflected signal or a simulated reflected signal derived from the simulated reflected signal as an output 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.

Abstract: A signal delay device includes a demultiplexer, D∈ delay means, D additional delay means, a multiplexer, and a control unit. For each delay means, a delay input and a demultiplexer output are connected, and a delay output and a multiplexer input are connected. For each additional delay means, an additional delay input is connected to a delay signal path, and an additional delay output and a multiplexer input are connected. The demultiplexer divides an input data word stream into parallel data word streams. Each delay means will delay the data words in the parallel data word streams. Each additional delay means will delay the data words in the delayed parallel data word stream by an additional delay time. The control unit controls the multiplexer such that an output data word stream corresponding to the input data word stream with a time delay is output.
