Numerical results

The least-squares reverse time migration algorithm is tested with synthetic data generated for the 2D HESS VTI and 3D SEG/EAGE salt models. In all the numerical examples, the synthetic data are generated according to a first-order acoustic VTI wave equation (Duveneck et al., 2008). A fixed acquisition geometry for both the sources and receivers are assumed, with the understanding that a different phase encoding strategy (Huang and Schuster, 2012b) is needed for a marine acquisition geometry.
