摘要： For example, a radar data compressor may include an input to receive input digital raw data comprising digital samples of received radar signals at a plurality of receive (Rx) antennas; a raw data compressor configured to compress the input digital raw data into compressed digital data, for example, by wiping off from the input digital raw data one or more wiped-off signals, e.g., based on a wipe-off criterion applied to the input digital raw data; and a compressor output to provide compressed data including the compressed digital data, and signal parameter information defining the one or more wiped-off signals.

摘要： Techniques are disclosed implementing two alternative approaches for adaptive beamforming for MIMO radar. The first of these includes a “reduced complexity” iterative adaptive approach (RC-IAA) algorithm, which uses two steps including a delay-and-sum beamforming step (DAS-BF) and an IAA step that is applied to the output generated by the DAS-BF step. A second technique is described that includes a “beam space” iterative adaptive approach (BS-IAA) algorithm, which uses three steps including a delay-and-sum beamforming step (DAS-BF), a region of interest (ROI) detection step that is applied to the output generated by the DAS-BF, and an IAA step that is applied to detected ROIs.

摘要： For example, a radar apparatus may include an input to receive radar receive (Rx) data, the radar Rx data based on radar signals received via a plurality of Rx antennas of Multiple-Input-Multiple-Output (MIMO) radar antenna; and a radar processor configured to generate radar information based on the radar Rx data by calibrating an antenna Mismatch (MM) of the MIMO radar antenna such that the radar information includes an Angle of Arrival (AoA) spectrum having a Peak Side Lobe Level (PSLL) of at least 30 decibel (dB).

摘要： For example, an apparatus may include an interference detector configured to detect interference in a radar Received (Rx) signal. The interference detector may include an input to receive Transmit (Tx) parameter information of a radar Tx signal, wherein the radar Rx signal is based on the radar Tx signal; and a processor configured to determine interference detection information of an interfering signal based on the radar Rx signal and the Tx parameter information. The interference detection information may include one or more signal parameters corresponding to a shape of the interfering signal, and interference level information to indicate a level of noise caused by the interfering signal in the radar Rx signal.

摘要： 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.
