| 英文摘要 | A numerical method for a nonlinear inversion problem for the 2D wave equation with a potential is discussed. In order to avoid the ill-posedness, we substitute a coupled system of one-way wave equations for the original wave equation. An iterative algorithm is constructed to improve the accuracy of the inversion. Numerical experiments are performed on several examples to examine the effectiveness of this method.
