An Improved Beamforming and its Application on the Noise Source Orientation of Moving Sources
Liu Xiandong · Noise and Vibration Control · 2007
The array signal processing method,which is used to orientate the sound source of the moving vehicle,was studied in this thesis.And a beamforming method based on spatial correlation function was advanced.The theory was researched in the simulation,and the results proved that the infection in precise of the rebuild result would be little,meanwhile,the needed microphones in the array would be much less.
