Directivity of acoustic vector array

Acoustic vector sensor with the electronic rotating directivity of dipole can effectively detect signal in the background of noises. More information can certainly be obtained by vector sensor array. The dipole and single-side directivity of single vector sensor or two elements vector array are simulated in computer in ideal condition and the directivity of single vector sensor is experimented in pool, the results of which are consistent with those of computer simulation. The results indicate that acoustic vector sensor can restrain coherent interference and incoherent interference.
