Abstract: The present disclosure relates to a radar emulator for testing a radar sensor. The radar emulator comprises a radar signal receiver configured to receive a radar signal having at least one characteristic. The radar emulator has a radar signal processor configured to process the radar signal received. The radar emulator has a response signal generator configured to generate a response signal to the radar signal received. The radar emulator has an interference signal generator configured to generate an interference signal that is synchronized with the response signal in time. The radar emulator has an adder configured to combine the interference signal and the response signal in order to obtain a combined output signal that comprises the response signal generated and the interference signal generated. Further, a method of testing a radar sensor is disclosed.

Abstract: The present disclosure relates to a radar emulator for testing a radar sensor in a testing environment with a potential distortion source. Further, a method of evaluating a testing environment is disclosed.

Abstract: A system for emulating radio frequency channels is provided. Said system comprises an input device for inputting a channel scenario, a channel coordinator device being in connection with the input device, and at least two channel emulator devices each being in connection with the channel coordinator device and for outputting a corresponding radio frequency signal to emulate the channel scenario. In this context, the channel coordinator device is configured to control each of the at least two channel emulator devices on the basis of the channel scenario and/or geometrical information with respect to the at least two channel emulator devices.

Abstract: The invention relates to a transceiver module for connecting an RF apparatus with one or more RF devices. The transceiver module comprises a baseband interface which is connectable to the RF apparatus for bidirectional communication of baseband signals, one or more RF interfaces, wherein each one of the RF interfaces is connectable to one of the RF devices, and a switching unit configured to convert baseband signal received at the baseband interface into one or more RF signals and to forward said RF signals to at least one of the RF interfaces according to a flexible mapping and vice versa. The transceiver module further comprises a control unit configured to control the switching unit, and a control interface which is connectable to the RF apparatus to receive control commands from the RF apparatus, wherein the control unit is configured to adapt the flexible mapping of the switching unit based on the received control commands.
