%X In this paper, the mechanism of the performance degration due to channel mismatching and sensor coupling in azimuthms and frequencies is analyzed. A new comprehensive calibration method that can compensate error by a known sound source is proposed. The method is easy to be implemented and the results of acoustic experiments in anechoic room show that offered method is effective.
