| Abstract | The seismic multiple attenuation is essential for improving the clarity and interpretability of subsurface images, as multiples can obscure primary reflections and complicate reservoir characterization. The Radon transform, with its ability to separate events based on moveout differences in the timeżoffset domain, is widely used for multiple attenuation in seismic data processing. This study evaluates the efficacy of Radon transform-based multiple attenuation, with a focus on comparing the performance of linear, parabolic, and hyperbolic Radon transforms. Despite their widespread use, Radon methods face challenges such as energy smearing and the limited availability of systematic comparative studies across transform types. To address these issues, we apply a sparse inversion framework designed to improve the separation of multiples and primaries and enhance energy focusing in the Radon domain. Synthetic seismic gathers with known event types are generated using wavelet modelling to evaluate the transforms, with performance assessed in terms of multiple suppression, primary preservation, and focusing sharpness. Results indicate that the inversion framework achieves enhanced focusing and interpretability, offering a practical solution to common Radon-based limitations and providing a rare systematic comparison of transform types for seismic multiple attenuation. |
