Abstract :
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.
