Abstract
A radar device including a transceiver unit that includes a plurality of receiving antennas and a plurality of transmitting antennas, a distance between at least two transmitting antennas being shorter than a greatest distance of distances between two receiving antennas, the transmitting antennas being vertically offset with respect to the receiving antennas. The radar device further includes a control unit, which is configured to activate the transceiver unit in order to operate the transceiver unit with the aid of a transmitting-side beam steering method.
Claims14
A radar device, comprising:
- a transceiver unit including a plurality of receiving antennas and a plurality of transmitting antennas, a distance between at least two of the transmitting antennas being shorter than a greatest distance of distances between two of the receiving antennas, and the plurality of transmitting antennas being vertically offset with respect to the plurality of receiving antennas;
- and
- a control unit configured to activate the transceiver unit to operate the transceiver unit such that a first subset of the plurality of transmitting antennas are operated according to a first operating mode and a second subset of the plurality of transmitting antennas are operated according to a second operating mode, the second subset being different from the first subset and the second operating mode being different from the first operating mode,
- wherein the plurality of transmitting antennas comprises a first transmitting antenna, a second transmitting antenna, and a third transmitting antenna, wherein the first transmitting antenna and the third transmitting antenna are aligned in a vertical direction, wherein the second transmitting antenna is situated between the first transmitting antenna and the third transmitting antenna in a horizontal direction, and wherein the second transmitting antenna is vertically offset by a predetermined distance with respect to both the first transmitting antenna and the third transmitting antenna.
A radar method, comprising the following steps:
- emitting radar radiation via a transceiver unit that includes a plurality of receiving antennas and a plurality of transmitting antennas, a distance between at least two of the plurality of transmitting antennas being shorter than a greatest distance of distances between two of the plurality of receiving antennas, the plurality of transmitting antennas being vertically offset with respect to the plurality of receiving antennas, and the transceiver unit operating a first subset of the plurality of transmitting antennas according to a first operating mode and a second subset of the plurality of transmitting antennas according to a second operating mode, the second subset being different from the first subset and the second operating mode being different from the first operating mode;
- and
- receiving reflected radar radiation via the transceiver unit,
- wherein the plurality of transmitting antennas comprises a first transmitting antenna, a second transmitting antenna, and a third transmitting antenna, wherein the first transmitting antenna and the third transmitting antenna are aligned in a vertical direction, wherein the second transmitting antenna is situated between the first transmitting antenna and the third transmitting antenna in a horizontal direction, and wherein the second transmitting antenna is vertically offset by a predetermined distance with respect to both the first transmitting antenna and the third transmitting antenna.
