A method and system for computer-implemented simulation of radar raw data, where the radar raw data are generated for a synthetic MIMO radar system including a transmitter array of several transmitters for transmitting radar signals and a receiver array of several receivers for receiving radar echoes of the radar signals. In this method, ray tracing of a radar signal sent from a preset transmitting position within the transmitter array and received at a preset receiving position within the receiver array is performed based on a 3D model of a virtual area adjacent to the MIMO radar system, where the ray tracing determines propagations of a plurality of rays within the radar signal from the preset transmitting position to the preset receiving position. The propagation of each ray is dependent on a first angle and a second angle describing the direction of a respective ray at the preset transmitting position. By using first-order derivatives with respect to the first angle and the second angle, propagations of a plurality of modified rays originating from a respective transmitter and received at a respective receiver are determined based on a linear approximation. The modified rays are processed in order to determine the radar raw data.

Method for computer-implemented simulation of radar raw data

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.
