Analytical path-summation imaging of seismic diffractions |
Keydar et al. (2009) describe pre-stack data imaging using path-integral formulation where the curvature of the diffraction hyperbola acts as a parameter describing different images being stacked. In this appendix, we derive a direct and analytical formula for unweighted pre-stack path-summation imaging based on the extension of velocity continuation technique to the pre-stack domain. Fomel (2003b,a) describes velocity continuation phase-shift for a pre-stack case:
