Vector-based excitation amplitude imaging condition for elastic RTM
J Zhou, D Wang - Journal of Applied Geophysics, 2017 - Elsevier
In recent years, many studies have focused on elastic reverse time migration (RTM). In
response to the problems associated with elastic RTM, we propose a new procedure for 2D
elastic multicomponent RTM. In this new method, decomposed P-and S-wave components
are obtained from the decoupled propagation of the source and receiver wavefields, which
allows the expedient calculation of the Poynting vectors and the incident and reflection
angles of the P-and S-waves. In addition, we deduce the vector-based excitation amplitude …
