AbstractWe extend seismic reflection Kirchhoff migration to receiver function study, to adapt to lateral velocity variation and improve the precision and resolution of receiver function migration. Model experiment shows that Kirchhoff migration can implement effective image of converted phases, remove the fictitious image, in contrast to ray‐based horizontal common‐converted‐point stacking method. We note that the imaging of dipping or curving interface is controlled by teleseismic azimuth, and receiver functions from different direction should be jointed to better resolve those complicated structures.
