The anisotropy reflectivity method based on wave theory considers the dynamic characteristics of seismic wave completely. The authors calculate and analyze synthetic seismograms for single interface theoretical model and heterogeneous anisotropic model respectively, and compare the dynamic characteristics of simulated results of computed Ruger and reflectivity method. It indicates that equal results are obtained for interface model by both methods, but the algorithm based on Ruger theory is influenced by varied sample intervalsfor the seismic AVAZ model, on the other hand, the wave-equation-based reflectivity method is not constrained by sample intervals because the input model is in depth domain.
