Research on Sound Source Imaging by Near-field Beamforming

Qingju Ning

Abstract

The conventional beamforming can only imaging sound source in far-field environment. In this paper,two different vector weightings are introduced to improve the effect of imaging based on near-field beamforming model. Inversely proportional weights beamforming and minimum variance distortion-less response beamforming are described. Two methods are simulated and their results show effectiveness.
