Abstract

This paper presents different ways to process acoustic data in order to localize targets.Beamforming and the MUSIC high resolution method have been tested for different propagation conditions during a NATO experimental campaign. This campaign,organized by DG /DCE/ETBS,has involved 6 countries in October 2002 in Bourges (France). Different localization methods were used to get the position of moving sources on a 4 kilometres circuit.The I.S.L. (French-German research institute of Saint Louis)has deployed a network of arrays nearby the circuit to test those localization techniques in different propagation conditions (day/night,early morning,...).Variance and mean error of the localization are compared for the different techniques used.
