Abstract
Based on the passive synthetic aperture principle, a new cylindrically focused beamforming localization method of moving sound sources based on vector sensor array suited for both narrowband and broadband signal is proposed in this paper. By establishing the measurement model of moving sound sources, calculating the localization accuracy versus error, and analyzing the experimental results of cabin model, the performance of this new method can be verified. A comparison between the focused beamforming localization results and the shell vibration measurement results proveds that the proposed method not only can obtain the localization results, but also can reflect the relative contribution of each coherent source.
