Conception d'un système de localisation de source sonore large bande par formation de voie pour des applications robotiques.


The work presented in this paper comes as a part of a project which aims at developing an auditory sytem for a mobile robot in order to localize a speaker. The proposed localization method is based on a convex optimization solution to wideband beamforming. A precise description of the optimization procedure together with the acquisition chain of the experimental testbed is given in order to bridge the gap between theory and practical implementation. Simulation results and comparisons with classical beamforming techniques are also provided.
