Abstract:Due to the limitations of acquisition conditions and costs, multi-source data may be incomplete or irregularly sampled. We propose in this paper a method for deblending and interpolating multi-source data. By introducing Mask operators, we use regularly sampled data deblending in irregularly sampled multi-source data deblending and interpolation and present its iterative framework. We first transform irregularly sampled multi-source data into a sparse domain, then use a shaping regularization in the sparse domain to achieve both deblending and interpolation. Tests on synthetic and field data demonstrate the validity and effectiveness of the proposed method.
