Optimal Beamforming with Spherical Microphone Array

구형 마이크로폰 어레이를 이용한 최적 빔형성기법

In this paper, optimum beamforming method using spherical microphone array is presented. Beamforming method has been recognized as an important study in localizing sound sources or visualizing acoustic fields in three-dimensional space. Its geometrical arrangement of sensors in space enables to process array signal to analyze the fields of interest by steering array response in three-dimensional.
