Abstract
In a method for operating a radar sensor, the unambiguousness range of the radar sensor is increased with respect to the range and/or the relative velocity by: transmitting multiple ramp sets by the radar sensor, the frequency ramps of the individual ramp sets each differing in one system parameter; adapting the sampling frequency during the detection of the radar echoes in such a way that a constant number of samples always results for each frequency ramp; and, to evaluate the radar signals, the spectra are periodically continued and compared to each other.
