Dynamic predictive deconvolution

WebThe delay time is the same as the propagation delay time of the slow Rayleigh wave and is proportional to the site of the crack. To efficiently detect the slow Rayleigh wave, three methods based on digital signal processing are proposed: wave shaping, dynamic predictive deconvolution, and dynamic predictive deconvolution combined with … WebSummary. Deconvolution is a general term for data processing methods designed to remove effects which tend to mask the primary reflected events on a seismogram. Some of the undesirable effects are produced by the earth, such as absorption, reverberation, ghosting and multiple reflections, whereas others are produced by the seismic sources …

WebPredictive deconvolution The problem is now to estimate a predictive filter f with the input traces. As the input traces have 512 samples, I took the length of the filter equal to 50 samples. The residuals of L 2 and L 1 deconvolution on the pure trace are similar (Figure ). As the input wavelet is minimum-phase, the L 2 deconvolution is efficient. WebINTRODUCTION. Deconvolution is a filtering process which removes a wavelet from the recorded seismic trace by reversing the process of convolution. The commonest way to perform deconvolution is to design …
