The predictive deconvolution can also be decomposed into these two steps. For multiples in larger offsets in the radial direction, multiples have a more periodic characteristic, which can be used in predictive deconvolution in radial domain. In this paper, we propose a method that uses multichannel predictive deconvolution to predict multiples in radial domain, followed by an adaptive subtraction to suppress the predicted multiples in x-t domain. The periodic characteristics of multiples at different offsets can be improved by radial trace transform. And the predicted multiples can be removed more effectively by the adaptive subtraction. Our example illustrates that our method can get better demul results in near and far offsets.
