Abstract
The paper proposes a method of passive leak detection for underwater pipelines by means of phased antenna arrays. It implies element-wise multiplication and addition of the output signals of individual array transducers. The proposed method provides a twofold increase in the resolution of the detection system in comparison with that obtained by conventional signal processing techniques and a high detection rate. The array pattern has been calculated numerically. The paper presents a version of the inspection system that implements the proposed method of signal processing using a phased antenna array, and the experimental results obtained.
