Abstract

In a method for frequency matching in an FMCW radar sensor, a plurality of frequencies, which are derived on various modulation ramps, and which respectively are shown by the radar sensor in a d-v space as geometrical locations, represent possible combinations of a distance d and a speed v of the respective object. In order to identify the objects located on the various modulation ramps, coincidences between the geometrical locations which belong to frequencies derived on various modulation ramps are searched for. The search for coincidences is initially restricted in a first step to a subspace of the d-v space, and in a subsequent step, the search is extended to other regions of the d-v space, while suppressing the frequencies that are associated with the objects found in the first step.
