MEASUREMENT OF THE SENSITIVITY PHASE-FREQUENCY CHARACTERISTICS OF HYDROPHONES BY THE RECIPROCITY METHOD

摘要

Some new approaches for phase calibration of hydrophones by the reciprocity method are considered. Uses of this method for measuring the phase angle of the sensitivity for the geometric and acoustic centers of a hydrophone and for determining the position of the acoustic center from its shift relative to the geometric center of a hydrophone are described. Results from an experimental test of these techniques are presented.
