Abstract
Some demonstrative aspects include radar apparatuses, devices, systems and methods. In one example, an apparatus may include a plurality of Transmit (Tx) antennas to transmit radar Tx signals, a plurality of Receive (Rx) antennas to receive radar Rx signals based on the Tx signals, and a processor to generate radar information based on the radar Rx signals. The apparatus may be implemented, for example, as part of a radar device, for example, as part of a vehicle including the radar device. In other aspects, the apparatus may include any other additional or alternative elements and/or may be implemented as part of any other device.
Claims20
An apparatus comprising:
- an input to receive radar receive (Rx) data, the radar Rx data based on radar signals received via a plurality of Rx antennas of a Multiple-Input-Multiple-Output (MIMO) radar antenna;
- and
- a processor to generate radar information by applying an Iterative Adaptive Approach (IAA) algorithm to the radar Rx data, the IAA algorithm configured for a multi-path scenario, in which the radar signals comprise multipath signals from a plurality of paths between the MIMO antenna and a radar object, wherein the IAA algorithm is configured such that the radar information comprises an Angle of Arrival (AoA) spectrum having, for the radar object, no more than two amplitude peaks, which are above −20 Decibel (dB), corresponding to the multipath signals.
A vehicle comprising:
- a system controller configured to control one or more vehicular systems of the vehicle based on radar information;
- and
- a radar device configured to provide the radar information to the system controller, the radar device comprising:
- a Multiple-Input-Multiple-Output (MIMO) radar antenna comprising a plurality of Transmit (Tx) antennas to transmit radar Tx signals, and a plurality of Receive (Rx) antennas to receive radar Rx signals;
- and
- a processor to generate the radar information based on radar Rx data, the radar Rx data based on the radar Rx signals, wherein the processor is configured to:
- generate processed radar data by applying an Iterative Adaptive Approach (IAA) algorithm to the radar Rx data, the IAA algorithm configured for a multi-path scenario, in which the radar Rx signals comprise multipath signals from a plurality of paths between the MIMO antenna and a radar object, wherein the IAA algorithm is configured such that the processed radar data comprises an Angle of Arrival (AoA) spectrum having, for the radar object, no more than two amplitude peaks, which are above −20 Decibel (dB), corresponding to the multipath signals, wherein the radar information is based on the processed radar data.
A product comprising one or more tangible computer-readable non-transitory storage media comprising instructions operable to, when executed by at least one processor, enable the at least one processor to:
- generate radar information by applying an Iterative Adaptive Approach (IAA) algorithm to radar receive (Rx) data, the radar Rx data based on radar signals received via a plurality of Rx antennas of a Multiple-Input-Multiple-Output (MIMO) radar antenna, the IAA algorithm configured for a multi-path scenario, in which the radar signals comprise multipath signals from a plurality of paths between the MIMO antenna and a radar object, wherein the IAA algorithm is configured such that the radar information comprises an Angle of Arrival (AoA) spectrum having, for the radar object, no more than two amplitude peaks, which are above −20 Decibel (dB), corresponding to the multipath signals;
- and
- provide an output based on the radar information.
