Abstract: A radar device. The radar device includes a transceiver apparatus that comprises at least three transmit antennas and at least three receive antennas or comprises at least two transmit antennas and at least two receive antennas having two-dimensional beam forming, wherein the transceiver apparatus is configured to emit radar radiation using the transmit antennas, to receive radar radiation using the receive antennas, and to generate radar data on the basis of the received radar radiation. The radar device further comprises an evaluation apparatus that is configured to establish whether radar radiation has propagated between the transceiver apparatus and the at least one target either directly or at least partly by way of at least one reflection by evaluating the radar data using a multitarget angle estimation model, wherein the multitarget angle estimation model takes the propagation of radar radiation along at least four paths into consideration.

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.

Abstract: A radar device. The radar device includes a transceiver unit that includes at least three transmitting antennas and at least three receiving antennas, the transceiver unit being designed to emit radar radiation with the aid of the transmitting antennas, to receive radar radiation with the aid of the receiving antennas, and to generate radar data based on the received radar radiation. The radar device further includes an evaluation unit, which is configured to estimate, by evaluating the radar data, at least one angle of at least one target using a 2-target angle estimation model, the 2-target angle estimation model taking the propagation of the radar radiation along four paths into account.

Abstract: A MIMO radar sensor. The MIMO radar sensor includes: a planar antenna array including two subarrays, in each of which multiple antennas are offset with regard to one another in a first direction, the subarrays being offset from one another in a second direction that is perpendicular to the first direction, the antennas of the two subarrays being more strongly focused in the second direction than in the first direction in each case, and at last two of the antennas being offset from one another in the second direction in at least one of the subarrays; a high frequency element, and a control and evaluation device. At least one subarray, in which the antennas are also offset from one another in the second direction, is symmetrical to an axis running in the second direction.
