Abstract
A method and device for determining a relative velocity of a radar target. An FMCW radar measurement is carried out in which a ramp-shaped frequency-modulated transmit signal is sent whose modulation pattern includes a first sequence of ramps succeeding one another offset by a time interval and at least one further sequence of ramps succeeding one another offset by the same time interval, the sequences being temporally interleaved. Received signals are mixed down to baseband signals. From the baseband signals, a two-dimensional spectrum is calculated separately for each of the sequences by two-dimensional Fourier transformation, transformation taking place ramp for ramp in the first dimension and transformation taking place via a ramp index in the second dimension. Based on the positions of a peak in at least two of the two-dimensional spectra of the baseband signals, a value is determined for the relative velocity of a radar target.
