In this paper we propose a robust beamforming technique which takes into account uncertainties and variations in the radiation pattern of the loudspeakers. The proposed technique is based on the solution of a robust least-square problem in which the propagation matrix is to some extent unknown. Both simulations and experimental results prove the validity of the proposed methodology in terms of directivity index and white noise gain.
