Abstract
A hybrid antenna apparatus for a motor vehicle includes steerable transmitter antennas and receiver antennas. The receiver antennas are arranged in sub-arrays for data adaptive and decision adaptive digital beamforming processing. A controllable phase shifter is coupled between each receiver antenna and a summation network in each receiver antenna sub-array. The plurality of sub-array summation networks are combined in mixers along with a receiver direction reference signal and output through A/D converters to the digital beamformer processor.
