In this paper, focusing beamforming algorithm is used to scan a measurement area to achieve passive location of the target noise source in the near field, which effectively solves the problem of noise source location in the near field. In this paper, the near-field focused beamforming method is developed based on the conventional beamforming method (CBF), MVDR beamforming method and MUSIC algorithm under far-field conditions. Finally, based on the near-field focused beamforming method, the sound source localization and recognition simulation of near-field stationary single frequency single point sound source is carried out.
