Seismic Interferometry by Deconvolution: Theory and Examples
Seismic interferometry is a field of growing interest in exploration seismology. In this paper we provide the theoretical basis for performing interferometry by deconvolution. We argue that for arbitrarily complicated models, deconvolution interferometry gives the causal scattering response between any two receivers. Interferometry by cross-correlation, on the other hand, gives both causal and ...
متن کاملGlobal-scale seismic interferometry: numerical validation of the acoustic correlation integral
Applying seismic reflection imaging on a global scale is hard due to the (locally) sparse source distribution. We approach this problem with seismic interferometry (SI). In this paper, we derive an expression for global-scale SI and test it on a simplified 2D acoustic lossless Earth model. When we use responses from sources placed all around the model, we can reconstruct the full and multiple-f...

متن کاملInterferometry by deconvolution, Part 1— Theory for acoustic waves and numerical examples
Interferometry allows for synthesis of data recorded at any two receivers into waves that propagate between these receivers as if one of them behaves as a source. This is accomplished typically by crosscorrelations. Based on perturbation theory and representation theorems, we show that interferometry also can be done by deconvolutions for arbitrary media and multidimensional experiments. This i...
متن کاملLarge - Scale Waveform Inversions of Surface Waves for Lateral Heterogeneity 1 . Theory and Numerical Examples
Surface wave scattering theory is presented as a new method for analyzing teleseismic surface wave data. Using surface wave scattering integrals the effect of lateral heterogeneity both on the surface wave coda generation and on the direct surface wave is described. Since the employed scattering theory for the forward problem is linear, the inverse problem can conveniently be solved in the leas...
