Wavelet-processing usage over the ultrasonic defectoscope signal at high-rise reverberation and noise interference

The paper describes the way to get a useful component of the ultrasonic defectoscope signal at high-rise reverberation and noise interference. The useful component is got with the thresholding of detail factors of a wavelet-decomposition. Probability of the 1st and 2nd type mistake is examined.
