Abstract

Summary

As there are several approximation methods available to rough surface scattering, we should have a clear understanding of their shortcomings and merits. modified a number of approximation methods for analytically describing rough surface scattering in irregular crustal wave guides, and carried detailed comparisons of the SH-wave field results with the harmonic plane wave incidence. In this study, we present further study on the limitations and accuracies of several semi-analytical methods, including the Kirchhoff approximation method, the Taylor expansion-based perturbation method, the Rytov phase approximation method, and the Born series method. Different from , we will focus on the modeling with a point source both in frequency domain and time domain. At last, we present a combined multiscale semi-analytical method consisting of three approximations.
