摘要

According to the WRW theory, a new quantitative bi-directional seismic illumination method, which is called “DUC bi-directional seismic illumination” is proposed. In order to improve the computational efficiency of this new method, DUC-DC bi-directional seismic illumination method is proposed. In the numerical experiments, the computational accuracy and efficiency of these two new methods are discussed and compared with the traditional bi-directional seismic illumination method. The result shows that the two-way wave-equation-based DUC bi-directional illumination result is very close to the theoretical bi-directional illumination result, so the correction of the DUC bi-directional illumination method is verified.
