Abstract
Systems, methods, and computer-readable media are provided for hybrid beamforming. An example method can include determining digital beamforming weights associated with a plurality of digital beamforming paths between digital beamformers and groups of analog beamforming circuits in a phased array antenna, each digital beamforming path being coupled to a group of analog beamforming circuits and each analog beamforming circuit being coupled to a respective set of antenna elements of the phased array antenna; determining analog beamforming weights associated with the groups of analog beamforming circuits, the analog beamforming weights comprising inverses of the digital beamforming weights; determining calibration offsets estimated to put analog beamforming paths associated with the groups of analog beamforming circuits in a desired phase and gain relationship to each other; and varying, based at least partly on the calibration offsets, a signal phase shift across the analog beamforming paths associated with the groups of analog beamforming circuits.
