%X The wave-equation finite difference algorithm is applied here as a solution for forward modeling and migration of receiver function. With the help of exploration seismology concepts, the equivalent velocity and traveltime equation are established, therefore the forward calculation and migration of receiver function are implemented by wave-equation finite difference method. The numerical calculation indicates that imaging of point diffractor and dome can be accomplished with high accuracy employing poststack wave-equation finite difference migration. Then the applicabilities for receiver function imaging between poststack finite difference migration and Kirchhoff migration are discussed according to numerical results. Finally, the effects on velocity error for imaging are analyzed.
