Patent number: 12146949Abstract: 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).Type: GrantFiled: November 24, 2021Date of Patent: November 19, 2024Assignee: GM CRUISE HOLDINGS LLCInventors: Jorge Julio Jácome Muñoz, Andre Giere, Özlem Karaca, Johanna Gütlein-Holzer

Transmitters (110, 112) 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.Type: ApplicationFiled: May 13, 2024Publication date: September 12, 2024Inventors: Andre Giere, Özlem Karaca, Johanna Gütlein-Holzer, Richard Johann Körber

Publication number: 20240036187Abstract: Various technologies described herein pertain to disambiguating velocity estimate data of a radar sensor system. First range estimate data can be computed based on samples from a period of a ramp for each ramp in a sequence. First velocity estimate data can be computed based on samples from a range bin across the ramps in the sequence for each range bin. For each of the ramps in the sequence, samples from a period of a ramp can be divided into a plurality of groups of the samples respectively from periods of subramps. The first velocity estimate data can be disambiguated to generate second velocity estimate data. The first velocity estimate data can be disambiguated based on the plurality of groups of the samples respectively from the periods of the subramps.Type: ApplicationFiled: July 30, 2022Publication date: February 1, 2024Inventors: Jessica Bartholdy Sanson, Andreas Barthelme, Andre Giere, Johanna Gütlein-Holzer

Publication number: 20230288555Abstract: A radar sensor system transmits a radar signal that comprises first pulses in a first frequency band and second pulses in a second frequency band. The radar sensor system receives a return of the radar signal from a target, wherein the return comprises the first pulses and the second pulses. The radar sensor system computes a coarse range estimate to the target. Based upon the coarse range estimate, the radar sensor system further computes a fine range estimate to the target, where a resolution of the fine range estimate is based upon a third frequency band that has a bandwidth greater than the first frequency band or the second frequency band.Type: ApplicationFiled: March 14, 2022Publication date: September 14, 2023Inventors: Jessica Bartholdy Sanson, Gustavo Adolfo Guarín Aristizabal, Andre Giere, Jorge Julio Jácome Muñoz
