The acoustic vector sensor (AVS) can measure the acoustic pressure field's spatial gradient, so it has directionality. But its channels may have nonideal gain/phase responses, which will severely degrade its performance in finding source direction. To solve this problem, in this study, a self-calibration algorithm based on all-phase FFT spectrum analysis is proposed. This method is "self-calibrated" because prior knowledge of the training signal's arrival angle is not required. By measuringdoi:10.1155/2018/1219670 fatcat:nwgjh3wigjhavbadro2efre3lu
