We design a highly accurate discontinuous-Galerkin-based strategy for computing wave traveltimes and amplitudes in heterogeneous anisotropic media, which is of major interest for a large range of applications in seismics, including seismic imaging. Our strategy, based on a general Hamiltonian formulation, handles complex boundary geometries such as topographies using deformed meshes and suitable radiation boundary conditions. Eikonal and transport equations are solved in order to reconstruct asymptotic Green’s functions and perform Kirchhoff migration.
