Abstract
FMCW radar sensor for motor vehicles, having at least one antenna element and a modulation device for feeding the antenna element using a frequency-modulated transmission signal, whose frequency periodically sweeps a frequency band, characterized in that the antenna element has multiple subelements, which are positioned in a vertical column and fed serially, and the modulation device is implemented for the purpose of variably setting the frequency position of the frequency band.

10. A driver assistance system for a motor vehicle, comprising:
-
an FWCM radar sensor including at least one antenna element, and a modulation device for feeding the antenna element using a frequency-modulated transmission signal whose frequency periodically sweeps a frequency band; wherein the antenna element has multiple subelements which are positioned in a vertical column and fed serially, and the modulation device is configured to variably set a frequency position of the frequency band; and a functional module which is configured to cause a change of the frequency position of the frequency band and to recognize blinding of the radar sensor when a received signal remains unaffected by the change of the frequency position.
