摘要

This manuscript presents a robust data-independent near-field beamformer using a linear microphone array. We consider a scenario with a desired sound source and an interferer; our goal in this manuscript is to provide a technique to extract the desired source signal while attenuating the interferer. We formulate the beamformer design problem as a convex optimization problem with additional constraints that aim at controlling the spatial response of the beamformer, with emphasis on the robustness of the approach to errors in the localization of the interferer sound source. We validate our approach through simulations.
