Abstract
AbstractIn this paper, a new type of analyzing wavelet named modified best matching seismic wavelet (called MBMSW wavelet) is proposed briefly, and the MBMSW wavelet's parameters are introduced. An amplitude attenuation formula is presented in time‐frequency domain, based on the differences between the energy absorbing of the seismic wave's higher frequency components propagating in anelastic medium and the lower ones. Using the MBMSW wavelet and the Morlet wavelet as analysing wavelets, the characteristics of seismic attenuation curves are extracted from the field and synthetic data and their time resolutions are compared, too. The robust of the method is tested by using the noised synthetic data.
