Abstract
Based on the engineering application of head-mounted acoustic source localization systems, the influence of a rigid sphere on UCA response is analyzed in detail utilizing the array model of a uniform circular microphone array located around a rigid sphere. In the eigenbeam space derived from the decomposed wavefield in spherical coordinates, DOA estimation of acoustic sources is realized based on a novel formulation of the popular subspace based algorithm, namely EU-Root-MUSIC (Eigenbeam-space Unitary Root-MUSIC). Computer simulations demonstrate that the proposed algorithm has the ability of estimating the DOA of multi-acoustic sources validly. Furthermore, it has the merit of low computational load and high performance as well as the ability of processing coherent acoustic sources.
