MODULAR PARALLEL BEAMFORMING SYSTEM AND ASSOCIATED METHODS

摘要

A beamforming system (400) comprising a plurality of modular beamformers (405A, 405B) is provided. The modular beamformers may be operatively coupled to each other (for example, in parallel). Each modular beamformer may comprise a plurality of signal generation units (105A/B/Z, 110A/B/Z) configured to generate digital signals. Each modular beamformer may further comprise a plurality of delaying units (115A/B/Z) configured to receive the digital signals and adaptively delay output of the digital signals. Each modular beamformer may further comprise a plurality of multipliers (410) assigned to the delaying units to generate conditioned digital signals by adaptively applying weights to the digital signals output by the plurality of delaying units. Each modular beam former may further comprise a plurality of summers (415A/B/C) configured to combine the conditioned digital signals to generate a phased array output signal.
