摘要:This paper makes full use of the characteristics of acoustic vector sensor (AVS), which can simultaneously measure both acoustic pressure scalar and particle velocity vector at single point in acoustic field. A new method is introduced by extending modified multiple signal classification (MMUSIC) to AVS, named as V-MMUSIC, which can be used to bearing estimation for coherent signals. Simulation results show that this method can achieve bearing estimation of coherent or unrelated signals and remove the port/starboard indistinct phenomenon. The proposed method can accomplish full spatial, unambiguous and small error bearing estimation in the low SNR.
