Abstract
Summary
This paper presents a 3D receiver de-ghosting method for aliased data. First, anti-aliasing interpolation and Radon transform methods that are relevant to the proposed algorithm are reviewed and discussed. Next, the proposed method is formulated: the method ranks the wavenumber components in the input data based on their relative energy and iteratively de-ghosts individual wavenumber ranges. In other words, de-ghosting is gradual and guided by this ranking. This allows a reduction of the size of the de-ghosting problem at each iteration, and also the removal of aliasing effects. Application of the proposed de-ghosting algorithm to a real data example provides satisfactory results.
