Detection of radar objects using a radar sensor of a motor vehicle
Abstract:
In a method for detecting radar objects with the aid of a radar sensor of a motor vehicle, a transmitted signal has a sequence of frequency modulations, to each of which a partial signal of a measuring signal is assigned; first information about the relative velocity and the distance of a radar object is ascertained based on a frequency spectrum of at least one of the partial signals; second information about the relative velocity and the distance of the radar object is ascertained based on a frequency spectrum of a time curve of values of frequency spectra of the partial signals at a frequency position of the radar object in these frequency spectra; and the relative velocity and the distance of the radar object are ascertained based on matching of the first information with the second information.
