PROCESS OF CALIBRATION OF SONAR ANTENNA UNDER CONDITIONS OF NATURAL WATER BASIN Russian patent published in 1995 - IPC

Abstract RU 2042283 C1

FIELD: metrological tests. SUBSTANCE: standard hydroacoustic target is mounted on calibrated sonar antenna. Hydroacoustic projector and standard measurement device are mounted opposite to sonar antenna on floating craft. Comparing output signals of hydroacoustic projector and standard measurement device one finds sensitivity of antenna by formula presented in description of invention. EFFECT: enhanced authenticity of calibration. 1 dwg
