Abstract: For example, an apparatus may include a scheduler configured to determine scheduling information to schedule radar transmissions of a radar device during a sequence of radar frames. For example, the scheduler may be configured to determine a burst-based frame setting to schedule a sequence of radar burst transmissions during a radar frame of the sequence of radar frames. In one example, the burst-based frame setting may include a setting of a burst gap duration. In one example, the burst gap duration may include a duration of a burst gap between first and second consecutive radar burst transmissions of the sequence of radar burst transmissions.

Abstract: Methods and apparatus to implement compact time-frequency division multiplexing for MIMO radar are disclosed. An apparatus includes an antenna array controller to: transmit a first signal via a first transmitter of a radar antenna array, the first signal having a first duration and modulated across a first frequency range; and transmit a second signal via a second transmitter, the second signal having a second duration and modulated across a second frequency range, the first and second durations including an overlapping period of time, the first and second frequency ranges including an overlapping frequency range. The apparatus further includes a signal separation analyzer to: determine a first echo received at a receiver of the radar antenna array corresponds to the first signal; and determine a second echo received at the receiver corresponds to the second signal.

Abstract: 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).

Abstract: 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.
