Spatial smoothing algorithm based on acoustic vector sensor array

Spatial smoothing algorithm is an effective means of decoherence, this array of sound scalar in the traditional spatial smoothing algorithm is proposed based on a vector array of space forward, backward and bi-directional smoothing algorithm, combined with vector array MUSIC algorithm to solve vector array DOA of coherent sound source is estimated, simulation experiments show that the vector array of spatial smoothing algorithm is no ambiguity about the advantages side, in the low SNR and small snapshot of the situation is better than the distinguished array of sound scalar performance.
