Abstract :
This paper proposes an application of calculation method of time-frequency correlation function to problems of pipeline leak detection and localization. Presented method avoids iterative procedures of detecting informative frequency range. The results of the study demonstrate better accuracy in leak localization as compared with other approaches by obtaining additional data on the signal and improving signal-to-noise ratio.
