Application of cross-correlation technique for multi leakage detection

The cross-correlation is a technique of non-destructive testing methods NDT, widely used to detect leaks from buried pipes in industrial and household facilities. This technique can be profitable when the anomaly signal has high power signal to noise ratio. In this work, we will use this technique to detect several leaks at the same time, by measuring two vibration signals provided from two detectors placed at the ends of the buried pipe, and properly estimate the delay of leak-related signals. The simulation results show that the effectiveness to detect the positions of several leaks.
