Abstract
Multichannel Singular Spectrum Analysis reconstruction (also named Cadzow filter reconstruction) offers a solution to the seismic data completion problem. Unfortunately, the method requires data deployed on a regular grid. Then, to apply MSSA, one first assigns seismic traces to a regular geometry via binning. The resulting volume of data contains a large number of empty bins that are reconstructed via the MSSA. We propose a modification to MSSA to avoid having to deploy the input data into regular bins. The new algorithm, Interpolated MSSA (I-MSSA), honours the exact spatial position of the seismic traces and iteratively reconstruct the data into a regular grid. The algorithm also incorporates an anti-alias operator that is required by our examples for simultaneous regularization and interpolation of 3D data with aliased and irregular trace positions.
