METHOD OF DETECTING HYDROACOUSTIC EFFECTS

摘要

FIELD: metrology.SUBSTANCE: invention relates to metrology, specifically to methods for detecting hydroacoustic noise emission. Method for detecting hydroacoustic actions comprises arranging hydroacoustic receiving hydrophone module in natural water body on anchor with a float, measurement of receiving module of parameters of a noisy object during further processing of such parameters on computer. Receiving hydrophone module is represented by high-sensitive sensor of angular speed. Angular speed is measured, obtained information is processed in a computing unit and based on determined value characterising measured hydroacoustic action by mathematical expression:where t is time for measurement; L is radius of rotation of sensor;- original fibre-optic gyroscope when measuring angular velocity sensor; S-linear displacement. Receiving hydrophone module can be equipped with flexible suspension with armature and constant length of rope. Length of fibre gyroscope hydrophone is up to 25 km.EFFECT: technical result is wider of range of detection of hydro-acoustic effects in low-frequency region.2 cl, 2 dwg
