In this paper, a novel optimization method based on the particle swarm optimization (PSO) algorithm for the array design is proposed. The PSO is introduced to search for the optimal microphone distribution on the Archimedes spiral line with the minimum sidelobe level and the narrow mainlobe width. Numerical simulation show the better performance of the array reconfiguration designed by means of PSO algorithm. Experiments in the semi-anechoic room demonstrate the effectiveness of the proposed scheme.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
