Abstract

A method for determining the source field by data of multiple-microphone measurements is developed. The method is based on the correlation analysis of acoustic fields. Under the assumption of delta-correlation of the source field, this approach allows the mathematical statement of the inverse problem to be fundamentally altered so that the problem becomes properly posed. In particular, this method allows simultaneously recognizing monopole and dipole components of the source field using measurements by a planar microphone array. The method is verified numerically using various test examples of simultaneous recognition of monopole and dipole components of the source field.
