Title
(EN) SYSTEM AND METHOD FOR ACOUSTIC LOCALIZATION OF MULTIPLE SOURCES USING SPATIAL PRE-FILTERING
(FR) SYSTÈME ET PROCÉDÉ DE LOCALISATION ACOUSTIQUE DE SOURCES MULTIPLES À L'AIDE D'UN PRÉ-FILTRAGE SPATIAL
Abstract
(EN)
A method, computer program product, and computer system for identifying, by a computing device, a plurality of sources, wherein a first source of the plurality of sources is a source of interest and wherein a second source of the plurality of sources is an interference source. The first source and the second source may be monitored simultaneously by implementing a spatial pre-filter for acoustic source localization.
(FR)
L'invention concerne un procédé, un produit-programme informatique et un système informatique permettant l'identification, par un dispositif informatique, d'une pluralité de sources, une première source de la pluralité de sources constituant une source d'intérêt et une seconde source de la pluralité de sources constituant une source d'interférence. La première source et la seconde source peuvent être surveillées simultanément par la mise en œuvre d'un pré-filtre spatial de localisation de source acoustique.
