A fast ramp frequency modulated continuous wave (FMCW) radar system () is described herein, where the fast ramp FMCW radar system is configured to employ velocity labeled multiplexing (VLM) in connection with generating detections for objects in a scene. Transmitters () in the radar system are assigned different velocity labels that corresponds to different phase rates of change of consecutive chirps in signals emitted by the transmitters. Approaches for generating detections based upon echo signals that correspond to the emitted signals are also described herein.

Radar system that uses velocity labeled multiplexing for generating detections

A phase modulated continuous wave (PMCW) multiple input multiple output (MIMO) radar system is described herein. The radar system is configured to compute range, velocity, and direction of arrival angle of objects relative to the radar system. The radar system includes several transmitting antennas and several receiving antennas, where selected transmitting antennas simultaneously transmit radar signals based on the same modulation signal. Per transmitting antenna, the transmissions are modulated with respective phase offsets on a per pulse repetition interval (PRI) basis. Hence, a coupling between phase shifts over PRI and transmitter positions is established. Effectively, then, each transmitting antenna is labeled with a velocity offset that corresponds to the phase rate of change assigned to the transmitting antenna. This approach is referred to herein as velocity-labeled multiplexing (VLM).
