Abstract :
The matrix pencil method is a MatLab friendly algorithm that generates results in real time. The technique was able to detect cracks in pipes whether they were on top of the pipe or on the bottom up to a SNR = 10dB. Also cracks in hidden and buried pipes were detected using the same technique.
