True Amplitude Wave Equation Migration Arising from True Amplitude One-way Wave Equations
One-way wave operators are powerful tools for forward modeling and inversion. Their implementation, however, involves introduction of the square-root of an operator as a pseudo-differential operator. Furthermore, a simple factoring of the wave operator produces one-way wave equations that yield the same traveltimes of the full wave equation, but does not yield accurate amplitudes except for hom...
متن کاملOne-way Wave Equation Modeling in Two-way Wave Propagation Problems
The exact, well-posed, one-way reformulation of Helmholtz-type wave equations and the generalized Bremmer coupling series are applied to the two-way, scalar, multidimensional Helmholtz equation of mathematical physics. These two constructions provide complementary ways of incorporating one-way wave equation modeling into two-way wave propagation problems. The mathematical framework, for the exp...

متن کاملTeleseismic waveform modelling with a one-way wave equation
S U M M A R Y It is now widely accepted that elastic properties of the continental lithosphere and the underlying sublithospheric mantle are both anisotropic and laterally heterogeneous at a range of scales. To fully exploit modern three-component broad-band array data sets requires the use of comprehensive modelling tools. In this work, we investigate the use of a wide-angle, one-way wave equa...
متن کاملHow to obtain true amplitude common-angle gathers from one-way wave equation migration?
True amplitude wave equation migration (WEM) provides the quality image of wave equation migration along with proper weighting of the output for estimation of an angularly dependent reflection coefficient, similar to the output of Kirchhoff inversion. In an earlier paper, Zhang et al. (2003) presented a true amplitude WEM for common-shot data in heterogeneous media. Here we present two addition...
