Abstract：In view of the problem of isochron building in the Kirchhoff migration and de-migration process,we analyze in this paper the theoretical basis and implementations of wavefront construction method in the process of the zero-offset isochron construction from the perspective of wavefront construction.Using the homogeneous medium model,we compare the isochron diagram calculated by the wavefront construction method with the theory isochron diagram at the different time steps to verify the accuracy of the method.Applications of this method to gradient,gradually varying and layered media,and Marmousi model demonstrate the effectiveness and the feasibility of this wavefront construction method.
