摘要：

The problem of analytical representation of the experimental complex frequency response of a hydrophone based on a model consisting of a lead line and a minimum-phase component is considered. The model takes into account the resonant properties of the hydrophone and the effect of sound diffraction on the active element. Algorithms for approximation of the complex frequency response by a fractional-rational function of a complex variable based on the data of the amplitude-frequency and (or) phase-frequency characteristics of the hydrophone are proposed. Examples of application of algorithms for processing experimental frequency characteristics of measuring hydrophones are given. The results obtained will simplify the calibration and greatly reduce the dimension of calibration data while maintaining the accuracy characteristic of working measuring hydrophones.
