Abstract


This paper is concerned with the problem of localizing multiple wideband acoustic sources. In contrast to existing techniques, this method takes the physics of wave propagation into account. 2D wave fields are decomposed using cylindrical harmonics as basis functions by a circular array mounted into a rigid cylindrical baffle. The obtained wave field representation is then used to serve as a basis for high-resolution subspace beamforming methods, most notably ESPRIT. It is shown that acoustic source localization based on wave field decomposition has the potential to unambiguously localize multiple simultaneously active wideband sources in the array's full 360 degrees field-of-view. ©2005 IEEE.
