Phased antenna array resolution enhancement for inspection of underwater crossings of pipelines

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

It is shown that available methods and devices for testing leakage of underwater pipelines do not allow to determine a defect location to high accuracy. In this view, it is suggested to receive the signals coming from acoustic emission by transducers of two-dimensional phased antenna array (PAA). It is demonstrated that an optimal way of PAA signal processing is the combination of pair multiplication with the subsequent algebraic summation of signals from several transducers. On the basis of the suggested method, the device PAL-121 was developed, which allows to determine a location of defects by means of two-dimensional representation of acoustic field of the inspection space.
