Abstract: 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.

Abstract: A method and a system for simulation-assisted determination of at least one actual echo point of an object, and a method and an emulation apparatus for emulating a detection target. Here, a predicted object reference point of the object and a predicted sensor device reference point of a sensor device, in particular a radar-based sensor device, are calculated on the basis of an actual object reference point and an actual sensor device reference point and a predicted echo point of the object is calculated on the basis of an emission characteristic of the sensor device, the predicted object reference point, and the predicted sensor device reference point. Moreover, a predicted relative relationship, in particular a spatial relative relationship, is calculated between the predicted echo point and the predicted object reference point.
