Abstract |
In ultrasonic nondestructive testing (NDT), ultrasonic pulse echo-sign of reflection pulse is often disturbed via Electronic noise, structure noise and so forth. with the intention to enhance signal detection and evaluation the ultrasonic defect echo signal should be denoised. In this paper, a new noise cancellation of empirical mode decomposition is proposed for enhancing signal-to-noise of the ultrasonic echo-signal. The ultrasonic echo-signal was gathered through experimental machine system of ultrasonic data acquisition. The sign-to-noise ratio became more enhanced approximately up to 6 decibel (dB) adopting this method and thus it is easy to identify the ultrasonic defected signal.
