Abstract: A system for creating an adjustable delay in an optical signal. The system has an input interface for receiving an optical input signal. The system has a first optical modulator configured to shift the frequency of the optical input signal depending on a setting of the first optical modulator, thereby generating a modulated optical signal. The system includes at least two frequency selective reflectors configured to reflect the modulated optical signal, thereby providing a reflected signal. The system has a control circuit that adapts the setting of the first optical modulator such that a frequency shift of the optical input signal introduced by the first optical modulator is set by the control circuit. The frequency shift introduced by the first optical modulator corresponds to an operational frequency of one of the at least two frequency selective reflectors associated with the setting of the first optical modulator.

Abstract: A LIDAR target simulation system for testing a LIDAR device is described. The LIDAR target simulation system includes a scenario generation circuit, a pattern detection circuit, a LIDAR simulation circuit, and a signal response generator circuit. The scenario generation circuit is configured to generate a test scenario for testing the LIDAR device. The pattern detection circuit is configured to receive at least one scan signal generated by the LIDAR device to be tested.

The signal response generator circuit is configured to generate a response signal to be received by the LIDAR device based on the at least one simulated scan signal of the LIDAR device and based on the test scenario.

Abstract: A radar target simulator for simulating radar targets is provided. The radar target simulator has an analogue-to-digital converter having a first clock generator and a digital-to-analogue converter having a second clock generator. The analogue-to-digital converter is configured to receive a radar signal transmitted by a radar system as an input signal, while the digital-to-analogue converter is configured to return an output signal to the radar system for simulation of the radar target. Further, the first and the second clock generator are configured to operate the analogue-to-digital converter and the digital-to-analogue converter at a different sampling rate in each case.

Abstract: A radar target simulator with no lower target distance limitation and continuous distance emulation is provided. Said radar target simulator comprises a receiving unit configured to receive a radar signal from a radar under test and to provide a corresponding receive signal, and a ramp slope estimating unit. In this context, the ramp slope estimating unit is configured to track the ramp slope of the radar under test on the basis of the receive signal.
