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 formulaeEFFECT: broader functional capabilities.1 dwg
