摘要：
Ultrasonic NDT signal de-noising effect is the key indicators to determine whether the pipe is defective.Orthogonal matching pursuit algorithm optimization process, the sampling signal and reconstructed signal by the method of least squares.Using Orthogonal Matching Pursuit Algorithm for the sampling signal to optimize and reconstruct. It is successfully to verify the OMP algorithm can recover the signal based on the MATLAB platform.Designed a signal de-noising processing module to help staff to determine pipeline defects conveniently,it achieved de-noising successfully.
