Abstract:
Methods, systems, computer-readable media, and apparatuses for radar processing based on a combination of analog beamforming, digital beamforming, and virtual arrays are described. In certain embodiments, a radar receiver receives signals simultaneously transmitted, i.e., concurrently, from a radar transmitter. Each transmitted signal corresponds to the same transmit signal, but with a respective phase being applied. The radar receiver generates, based on the received signals, a virtual array response corresponding to an array of virtual antennas. The virtual array response covers a subset of directions within a field of view to be scanned. In some embodiments, the transmissions from the radar transmitter are generated using analog beamforming, and the virtual array response generated using digital beamforming. In other embodiments, the transmissions from the radar transmitter are generated using digital beamforming, and the virtual array response generated using analog beamforming.
