Comparative Effectiveness Analysis of Wiener – Levinson Deconvolution and Radon Transform for Suppressing the Reverberation Noise in Shallow Water Environments

Abstract

A study of the suppression of intense reverberation noise during onshore 3D CMP seismic surveys in areas with a developed hydrographic network was conducted. Using as an example an area with extensive river network, a comparative analysis of two noise suppression approaches was performed: predictive Wiener-Levinson deconvolution and high-resolution Radon transform. It is shown that the spatial non-stationarity of the waveguide in river conditions limits the effectiveness of predictive deconvolution. A two-step processing scheme for the highresolution Radon transform with adaptive parameterization of the signal/noise separation boundaries is proposed. The results of visual analysis demonstrate a significant attenuation of the reverberation noise while preserving useful wave components.
