Intelligent Household Application Base on Mobile Phone the Ultrasonic Nondestructive Testing Technologybased on the Signal Processing Technique

The ultrasonic nondestructive detection measurement techniques is so successful, it not only based on production and income measures of the wave, but also to the basis and the shrinkage of the waveform of get signal processing. Although the traditional time domain method can successfully sure small cracks, but you can't estimate the size of the crack, especially in the strong scattering noise to the influence of the after. Experimental results show that this algorithm not only has excellent performance, still can strong presence of noise in the signal processing, also can succeed estimate the size and location of the crack. In addition, this algorithm can be applied to ultrasonic nondestructive signal data compression.
