Abstract
The following problem is considered in the underwater acoustic. At the same time the location of the hydrophone acoustic center must be known respect to the reference point. A method is proposed for determining the position of the acoustic center of a hydrophone relative to a selected reference center. The scheme of the experiment to determine the position (displacement) of the acoustic center of a hydrophone relative to the geometric center of the active element contour is described. The results of the experiment for different types of hydrophones are presented and the sources of measurement uncertainties are discussed. It is shown that taking into account the displacement of the acoustic center makes it possible to improve the accuracy of the phase calibration of hydrophones. The proposed method can be used in the field of the underwater measurement of the sound pressure receiver sensitivity.
