A Fast Beamforming Method to Localize an Acoustic Emission Source under Unknown Wave Speed

A Fast Beamforming Method to Localize an Acoustic Emission Source under Unknown Wave Speed

The beamforming method is capable of localizing the acoustic emission source in a large-scale structure but its accuracy relies strongly on the assumed propagation speed and it is quite time consuming to apply in online monitoring. This paper proposes a fast beamforming method to localize an acousti...
