Abstract :
The application of wavelet transform for a high resolution ultrasonic measurement is described. Wavelet transform is one of the time-frequency analysis methods and is suitable for finding abrupt changes in the waveform. The authors have been trying to apply this method for detecting separating positions of scatterers in random media. It has been found by calculations and experiments that this method can be used for characterization of random media
