Abstract :
Through the technology of using acoustic emission signal to extrapolate the AE source; this paper describes the basic theory of the near-field uniform linear array model and the Multiple Signal Classification algorithms. Combined with the property of AE monitoring, we present this algorithm can be applied to the spatial position estimation of AE source. The simulation result proves that the MUSIC algorithm based on the near-field uniform linear array will be effectively used in the estimation of AE source.
