Study of an octahedral antenna for both sound pressure level estimation and 3D localization of multiple sources

This study deals with localization and characterization of multiple sources by mean of an octahedral array processing. We show how correlations enable to both localize more sources that the number of sensors and estimate their sound level pressure simultaneously. The theoretical basis of the algorithm, based on analytical geometry and time differences of arrival, is explained for the broad-band sources in the far field and experimented in anechoic conditions. The localization error due to uncertainty of some physical measurements and numerical recording is studied. Results and limitations of the proposed method are discussed.
