Examples disclosed herein relate to a sensor fusion system for use in an autonomous vehicle. The sensor fusion system has a radar detection unit with a metastructure antenna to direct a beamform in a field-of-view (“FoV”) of the vehicle, an analysis module to receive information about a detected object and determine control actions for the radar detection unit and the metastructure antenna based on the received information and on environmental information, and an autonomous control unit to control actions of the vehicle based on the received information and the environmental information.
