Apparatus and method for providing probabilistic additive gain, calibration, and linearization in a phased array using single bit sources

An array of antennae includes a monobit transmitter to insert dither into a transmit signal to form a dithered transmit signal. Monobit receivers process received signals that are combined with the dithered transmit signal to form composite received signals. Digital down converters process the composite received signals to form down converted received signals. A beamformer circuit processes the down converted received signals to form recovered signals.
