Abstract: A method for detecting critical transverse movements. The method includes the following steps: emitting a CW radar signal and generating radar data based on the received reflected CW radar signal with the aid of a radar device; ascertaining collision-relevant spectral ranges of the radar data as a function of an ego velocity of the radar device; ascertaining a time dependency of a relative velocity and of an object angle of an object by evaluating the radar data in the ascertained spectral ranges; and detecting a critical transverse movement of the object using the time dependency of the relative velocity and of the object angle of the object.

Abstract: A method for signal evaluation in a locating system that includes multiple radar sensors whose locating ranges overlap one another. The method includes evaluating the signal of a first of the radar sensors and identifying distance cells that are not empty, for at least one of these distance cells: selecting a second of the radar sensors and determining a distance range in which the objects situated in the distance cell would have to be situated from the viewpoint of the second radar sensor, and classifying the object configuration in the distance range, based on the signal of the second radar sensor.

Abstract: A method for checking the plausibility of an initially known transverse movement of an object. The method includes: emission of a radar signal having constant signal frequency, and reception by a radar device of reflections of the radar signal having constant signal frequency; and checking the plausibility of the transverse movement of the object by analyzing frequency ranges corresponding to the transverse movement in a spectrum of the reflected radar signal having constant signal frequency.

Abstract: An analysis of radar signals, in particular of radar signals, which are received by a plurality of ULA antennas. By applying different beam formations to the radar signals of the individual ULA antennas, beamforming is used to compensate for dips in the gain.

Abstract: A method for detecting misalignment of a radar sensor positioned on a vehicle. A Doppler spectrum for the radiation emitted and received by the radar sensor is ascertained. For at least one frequency bin of the Doppler spectrum, an angle of incidence is determined in at least a subinterval. The determined angle of incidence is compared to the angle of incidence expected for the frequency bin. A misalignment of the radar sensor is detected as a function of the difference of the measured angle of incidence from the expected angle of incidence.
