| A reflection seismogram can be represented as a convolution of a source wavelet with a set of reflection coefficients. In a standard model these coefficients are scalar and real impulses. For all plane waves, displacements are phase shifted in post-critical angles. In this case reflection coefficients can be complex and the scalar deconvolution does not remove distortions perfectly. To overcome this problem, it has been attempted to examine an analytical technique [i.e. Analytic Minimum Information Deconvolution (AMID)] that can remove distorted effects from seismograms. The necessary codes have been written for applying AMID technique to synthetic and real data. Using computer programs in seismology (Herrmann, 1996), the necessary synthetic seismograms are generated for a specific structural earth model. 10% random noise is added to the synthetic seismograms and the output of AMID filter is investigated for different source - receiver offsets. The results of this study shows the ability of AMID for elimination of random noise and Moho phase detection | ||
