Deconvolution with multiple gates (or windows) commonly is used to correct for absorption loss of high frequencies. This approach requires that the deconvolution operators be derived from windows that are smaller than usual. Some of those windows might be too short to meet the requirements necessary for the statistical assumption that the reflectivity be random within the window. In addition, use of short windows often results in phase distortions at the zones of overlap. However, some processing systems include methods for designing smoothly varying minimum-phase inverse filters that correct for those deleterious effects.
