METHOD OF MEASUREMENT OF VERTICAL DISTRIBUTION OF SPEED OF SOUND IN THE AQUATIC ENVIRONMENT

摘要

Method of measuring the vertical distribution of the velocity of sound in an aqueous medium comprising that emit in the aqueous medium in the direction of the bottom pulse acoustic signal with the first and the second closest on the carrier frequency, measured speed of sound at the horizon source of acoustic vibrations, characterized in that the carried parametric radiation a vertical directivity characteristic, receiving the acoustic signal at the source of the scattered acoustic waves inhomogeneities aqueous medium with the first and second carrier frequencies, the measured value of the sound velocity of an acoustic source on the horizon, the current values ​​of the phase difference between the received reference signals and carrier frequencies determined desired vertical distribution of the velocity of sound in the aqueous medium.
