Experimental Study on a Target Direction Finding Algorithm for Gas Leakage Detection in Underwater Structures

Abstract

Aiming at the application scenarios of underwater structure gas leakage detection in marine oil and gas development process, the power spectrum characteristics of underwater structure gas leakage radiation noise are analyzed. An new target direction finding algorithm is proposed, and the gas leakage detection-finding software is designed. Then, the test platform is built to complete the experimental study of underwater structure gas leak detection. The test results show that the new target direction finding algorithm used in this paper is compared with the conventional beam forming algorithm. The difference between the maximum beam energy value and the sub-maximum value is bigger, indicates that the target’s resolving power is strong, which effectively improves the detection capability of gas leakage targets in underwater structures.
