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. When a data rate of an input signal changes, the multi-channel multi-phase digital beamforming method can perform weighted synthesis for the signal at different sampling rates by changing a quantity of signal phases without changing a processing architecture. Based on a multi-phase finite impulse response (FIR) filtering technology, a fractional multiple delay processing architecture that can flexibly adapt to a plurality of phase quantities of the input signal is proposed.
