| Abstract: | Signal processing is important part of magnetic flux leakage (MFL) in nondestructive testing(NDT) of Oil-Gas pipeline. There are many human effects in the MFL signal processing. This paperdescribes the factors disturbing the MFL signal, and parents the procedure and main method of MFLsignal intelligent processing which can improve the objectivity, veracity and coherence of pipeline MFLtesting result. The level and the trend of development of the MFL signal processing are also introduced. |
