| 摘要 |
The invention relates to a method for unambiguously determining a range and/or a relative speed of an object with respect to a motor vehicle (1) by means of a frequency modulation continuous-wave radar device (3, 4) belonging to the motor vehicle (1), wherein, in a measuring cycle, a predetermined sequence of frequency modulated signal pulses (23) is transmitted by the frequency modulation continuous-wave radar device (3, 4), by means of which a range of unambiguity (REin) for the range and/or a range of unambiguity (VEin) for the relative speed is determined, wherein, for at least two successive measuring cycles, mutually different ranges of unambiguity (REin) for the range and/or mutually different ranges of unambiguity (VEin) for the relative speed are defined, and the range and/or the relative speed is determined by using respectively at least one measured value for the range and/or for the relative speed from each measuring cycle. |
