An acoustic vector sensor provides measurements of both the pressure and particle velocity of a sound field in which it is placed. These measurements are vectorial in nature and can be used for the purpose of source localization.
A straightforward approach towards determining the direction of arrival (DOA) utilizes the acoustic intensity vector, which is the product of pressure and particl evelocity. The accuracy of an intensity vector based DOA estimator in the presence of sensor noise or reverberation has been analyzed previously for the case of a white source signal. In this paper, the effects of reverberation upon the accuracy of such a DOA estimator in the presence of a colored source signal are examined. The analysis is done with the aid of an extension to Polack’s statistical room impulse response model which accounts for particle velocity as well as acoustic pressure. It is shown that signal colorations brings about a degradation in performance.
