FIELD: underwater acoustics, calibration of measurement hydroacoustic arrays. SUBSTANCE: tested hydroacoustic array is placed into hydrochamber with reference hydrophones and hydroacoustic projectors. Acoustic field modelling field of plane wave with incident angle equal to zero failing on array is formed in hydrochamber with the aid of projectors. Sensitivity of hydroacoustic array is determined by comparison method. EFFECT: improved authenticity of method. 1 cl, 1 dwg
