The accuracy of the background velocity analysis is critical to image the subsurface structure in seismology. Wave-equation migration velocity analysis using source-domain common-image gathers require
The Radon transform serves as a critical tool for multiple suppression as well as high-precision imaging for seismic primary reflections, while its focusing capability directly affects the outcomes of
