Abstract
An FMWC radar sensor for motor vehicles, having a high-frequency oscillator, which is developed to generate a frequency-modulated transmit signal that has a periodically repeating series of modulation sequences having different modulation patterns, and having an evaluation device for evaluating the received radar echo according to the FMCW principle, wherein the series of the modulation sequences includes a special class of modulation sequences whose duration is longer than that of any other modulation sequence not belonging to this class and whose frequency swing is smaller than that of any other modulation sequence, and the evaluation device is developed to carry out a measurement of the ego velocity of the vehicle on the basis of a radar echo that is received from non-moving objects during the modulation sequences that belong to the special class.
