中文摘要	The Acoustic Vector Sensor can measure both pressure and particle velocity information of acoustic field at a point in space. By using the acoustic pressure and particle velocity information, a single AVS can get the unbiased estimation of target’s bearing. But when the phase of each channel is inconsistent, the estimation precision will be badly affected. In order to solve this problem, this paper uses the instantaneous correlation integral as a preprocessing algorithm. After the instantaneous correlation integral, the phase of each channel becomes the same, and the signal-to-noise (SNR) ratio of the input signal is improved, which can guarantee the effectiveness of target bearing estimation. Theoretical analysis and simulation results verify the effectiveness of this method.
