Abstract: A multi-channel multi-phase digital beamforming method and apparatus is provided. The multi-channel multi-phase digital beamforming method includes following steps: S1: pre-configuring a delay filtering coefficient storage table; S2: calculating a filter coefficient and a weighting coefficient; and S3: performing weighted synthesis and filtering processing on a multi-phase signal to form a multi-phase digital beam.
