A method and a device for determining a radar cross section, a method for training an interaction model, a radar target emulator for manipulating a radar signal, and a test facility for a vehicle are described herein. The propagation of a virtual radar signal is simulated on the basis of an interaction model in a simulated environment scenario that contains the simulated radar target. An interaction of the virtual radar signal with the simulated radar target is modelled such that a physical variable, characterizing the virtual radar signal, is divided into a directional component that corresponds to a directed scattering of the virtual radar signal and into a diffuse component that corresponds to an isotropic scattering of the virtual radar signal. A value of the physical variable is determined at a receiver point in the simulated environment scenario, taking into account the directional component and the diffuse component, and the radar cross section of the simulated radar target is derived from the determined value of the physical variable at the receiver point.
A method for determining a radar cross section of a simulated radar target comprising the procedural steps:
