| Abstract: | It is significant to detect defect in muhilayered structure of aircraft. This paper design a Pulsed eddy current nondestructive testing system. Extracting the signal feature such as peak amplitude, time - to - peak and time - to - zero crossings that relies on the signal processing, it made the quantitative detecting coming true. Finally, the conclusion is validated by farther experiment. |
