Crosstalk attenuation for imaging of multiples based on angle gather residual moveout analysis

Imaging of multiples, as a supplement to imaging primaries, can provide wider range subsurface illumination. Therefore, it more detailed information on structures. However, multiples suffers from crosstalk issues generated by unrelated events. Many strategies have been proposed attenuate crosstalk, among which the angle domain Radon attenuation algorithm achieves good application effect. In domain, true is flat, while events moveouts. convenient identify in gathers using transform. conventional transform lacks quantitative description for gathers, would affect accuracy attenuation. this paper, residual moveout kernels are derived with multiples. First, two types (RMO) equations based causality crosstalk. A three-layer model used verify correctness analytical solutions. Then, equations, be attenuated respectively domain. Synthetic experiments demonstrate that RMO effectively
