Abstract: A method for improving an evaluation of object identification of a radar device of a motor vehicle. A first map is generated of the surroundings of said surroundings by a LiDAR scanner. A first object identification is performed on the basis of the generated first map of the surroundings by a first identification apparatus. A ground-truth model is created of the surroundings on the basis of the performed first object identification by the first identification apparatus. A second map is generated of the surroundings of the surroundings by the radar device. A second object identification is repeatedly performed using alternative object identification algorithms on the basis of the generated second map of the surroundings by a second identification apparatus of the radar device. A radar model is created of the surroundings on the basis of the repeatedly performed second object identification by means of the second identification apparatus.

Abstract: A method is provided for operating a radar system of a vehicle. The radar system has at least one radar sensor for detecting at least one target outside the vehicle. A prediction of an ego-velocity (vEgo) of the vehicle is performed, so that a prediction result is determined. A classification for classifying the at least one detected target as a stationary target is then performed using the prediction result, so that a classification result is determined. One of at least two estimation methods is then selected for an estimation of the ego-velocity (vEgo), such that the selection is dependent on an evaluation of the classification result.

Abstract: A method for operating a radar sensor in which the radar sensor is provided with a signal generating device. The signal generating device generates an outgoing signal as a radar signal that is to be emitted. The radar sensor also includes a signal receiving device for receiving and processing received signals as reflected radar signals. The outgoing signal is generated within a predefinable frequency band. The received signals are monitored for the presence of an interference disruption. When an interference disruption has been detected, the frequency band for the generation of the outgoing signal is at least temporarily reduced in terms of the bandwidth.
