Shot-domain RTM

The dataset is first migrated with conventional shot-domain RTM method after preprocessing, and the image is shown in Figure (a), which contains strong artifacts near the shallow reflectors, which are caused by head waves and diving waves (Liu et al., 2011). In the bottom right corner of the image, there are low-frequency horizontal stripes. In the zoom views (Figures (a) and (a)), the RTM image shows double-dipping near-vertical artifacts.
