| Abstract: | Researching non Gaussian signal is a new field of signal processing.The authors describe the principle of the leakage detection of underground conveying watering pipelines,and use Bispectrum Feature Time Delay Estimation to estimate the position of the goal,and then to locate it in the leakage location of underground conveying water pipelines.The experimental results indicate that high order spectrum has great potentialities in the leakage detection of underground conveying water pipelines. |
