Cylindrical array beamforming
WebA beamforming method for cylindrical array based on synthetic pattern of subarray Abstract: A new approach to beamforming for a cylindrical conformal array geometry is developed. We first derive a deterministic expression that describes the beam pattern of arbitrary … Webin cylindrical array case. Accordingly, the summations in computation of beamforming weights (Equations (8) and (10)) are also truncated top and 2p −1 terms, respectively. However, the numerical weakness of the beam-forming algorithm is that the beamforming weight is inversely pro-portional to mode strength, which rapidly approaches zero when
