Abstract
In this paper, the feasibility of cross-time-frequency spectrum based leak location of gas pipeline using fiber taper sensor is tested. The cross-Wigner distribution of the two signals collected on either side of the leakage point is used to extract the time difference of arrival between the two signals and the corresponding frequency. This information is then used to estimate the leak location. The distance between the leak and Sensor 1 tested was 0.79 m. The percentage error obtained from the estimation was as low as 5.29 percent.
