FIELD: hydroacoustics; metering noise-emission parameters of various objects in natural water reservoirs. SUBSTANCE: antenna is built around one interferometer; fiber-optic sensing elements are multiplexed on its basis. Each sensing element of antenna is subjected to individual amplitude or frequency modulation followed by demodulation of antenna output signal at desired frequencies. EFFECT: reduced cost and simplified design of antenna optical system. 2 cl, 5 dwg
