True Amplitude Thin Slab Multi-One-Way Inversion - Application to Marine-Type Seismic Data

True-amplitude wave-equation migration can be obtained by using a modified imaging principle and a multi-one-way scheme. In order to avoid the artifacts of the multi-one-way scheme due to the turning rays, a thin-slab approach is investigated. A wave-equation inversion formula is proposed to recover the reflectivity. Under the high-frequency approximation, it is similar to the pseudo-inverse formula. This formula is applied on a synthetic and real example.
