METHOD OF DETERMINING AMPLITUDE-FREQUENCY AND PHASE-FREQUENCY CHARACTERISTICS OF FIELD SENSITIVITY OF HYDROACOUSTIC RECEIVER Russian patent published in 2016 - IPC H04R29/00 

FIELD: physics.

SUBSTANCE: stand comprises a radiator, a reversible transducer and a calibrated hydroacoustic receiver, which are arranged in a measuring reservoir at the same line and spaced apart by a certain distance. The radiator and the reversible transducer are alternately excited by an electrical signal and field transfer impedances of the radiator-calibrated receiver pair, radiator-reversible transducer pair and the reversible transducer-calibrated receiver pair are determined. The amplitude-frequency and phase-frequency characteristics of the field sensitivity of the calibrated hydroacoustic receiver to sound pressure are calculated using a reciprocity method formula. The amplitude-frequency and phase-frequency characteristics of the field sensitivity of the hydroacoustic receiver to hydroacoustic field vector values are determined using formulae

EFFECT: broader functional capabilities.
