Abstract
A method is presented for the prediction and attenuation of long‐period water‐layer multiples based on an adaptive multichannel lattice algorithm. The multichannel approach can be viewed as a generalization of two‐dimensional linear prediction. The multichannel linear least‐squares prediction problem is reviewed briefly and the performance and limitations of the algorithm are demonstrated on two different marine data sets with different properties of the simple and peg‐leg multiple system. The algorithm works well even on problematic data sets and is very easy to apply.
