Abstract
Methods of in-held absolute calibration of multi-element acoustic ante nnas are considered. Requirements imposed on the calibration procedure s are formulated, and the calibration accuracy is estimated. A new cal ibration method that uses the statistics of bottom-reflected signals i s proposed, practical calibration schemes are recommended, and data of deep-ocean experimental measurements are presented.
