英文摘要	A new algorithm of multi-dimensional localization and tracking of multiple sources in reverberant acoustic environments is proposed. The TDOA estimation based on blind source separation and fusion of multiple microphone pairs for localization are investigated. TDOA-based acoustic source localization approaches suffer from a pairing problem in the case of multiple dimensions and multiple sources. In this paper, one solution was proposed based on a Gausaian likelihood function to pair TDOAs,which can be used to localize multiple moving sources in two dimensions only using two microphone pairs. Moreover, the proposed method is combined with a particle filter for tracking multiple moving sources. Simulation experimental results demonstrate the effectiveness of the proposed scheme.
