Wavelet Analysis – A New Approach to Processing of Acoustic Full Waveforms

P062 WAVELET ANALYSIS – A NEW APPROACH TO PROCESSING OF ACOUSTIC FULL WAVEFORMS Summary 1 In this paper wavelet transform was assessed as a new tool for processing of acoustic full waveforms. The goals of the research were to: identify and separate P S and Stoneley wave packages determine arrivals and durations of respective waves and eliminate low- and highfrequency noise from acoustic wavetrains. The basis of Discrete (DWT) and Continuous Wavelet Transform (CWT) are introduced and the way of applying wavelet analyses to processing of acoustic full waveforms is presented. Evaluation was done on the basis of slowness. Transit
