Abstract: An automotive testing method includes acquiring radar sensor data responsive to a radar excitation signal generated by a radar transmitting unit, forwarding the acquired radar sensor data to an electronic system of a radar receiving unit, generating radar data from the forwarded radar sensor data, and processing the radar data, wherein the step of acquiring radar sensor data includes generating synthetic radar data, the synthetic radar data being forwarded as radar sensor data to the electronic system of the radar receiving unit, where the synthetic radar data includes reflection signals, preferably all reflection signals, in a complex time series, that succeed each other and have the same temporal behavior within a synthetic period that lasts at least an order longer than a time period of the radar excitation signal.
