An apparatus is for generating an emulated radar reflection signal of a target. The apparatus includes a radar detector configured to detect a radar signal frame emitted by a device under test (DUT), an emulation transmitter configured to generate an emulated radar reflection signal of a target being emulated, and a processor configured to generate control signals which control the emulation transmitter according to at least one characteristic of the target being emulated. The processor is further configured to determine a current radar parameter among plural possible radar parameters of the radar signal frame of the DUT, and to adapt the control signals which control the emulation transmitter according to the determined current radar parameter of the radar signal frame of the DUT.
