英文摘要Diffractions are the seismic response of geologic discontinuities, such as faults, pinchouts and small scattering objects, in general all objects which are small compared to seismic wavelength. Diffraction imaging has a great potential to detect these structural details beyond the classical Rayleigh limit of half a seismic wavelength. However, diffractions are essentially treated as noise in conventional seismic processing sequence, such as Normal Move-Out and stack. Moreover, the energy of diffractions is typically one or two orders of magnitude weaker than that of specular reflections. Therefore, the separation of diffractions is a challenging issue.
