RECONSTRUCTION OF THE SEMBLANCE SECTION FOR THE CRUST AND MANTLE REFLECTION STRUCTURE BY WIDE-ANGLE REFLECTION SEISMIC DATA
由宽角反射地震资料重建壳幔反射结构的相似性剖面

Since the shots and receivers are sparse in active wide angle seismic exploration, we use wide angle reflection seismic data to reconstruct the semblance section of reflection structure in the crust and mantle based on the diffraction theory. The travel time conditions for reconstructing the semblance section are calculated using the reciprocity principal, and the travel time field from shots and receivers are computed using Eikonal solvers which have the advantage of high efficiency and accuracy. The results from processing real wide angle reflection seismic data in southeastern China showed that this method can improve the horizontal consistency of reflection events compared with CDP mapping.
