Multi-wave prediction method based on adaptive weighting

The invention provides a multiple prediction method based on adaptive weighting, and aims to solve the problems that in the prior art, only multiple contribution gathers are simply superposed during multiple prediction, obvious difference of development conditions of different offset multiples is not fully considered, the development of the multiples is relatively strong at a near offset, and the development of the multiples is relatively strong at a far offset. The invention provides an adaptive weighted stacking three-dimensional wave equation multiple prediction technology aiming at different near-middle-far offsets, which can improve the accuracy of multiple prediction, effectively improve the accuracy of multiple prediction and improve the prediction accuracy of multiple. And a high-quality multiple wave model is provided for a subsequent multiple wave subtraction stage. 本发明提供了一种基于自适应加权的多次波预测方法，现有方法在预测多次波时只是对多次波贡献道集进行简单的叠加，没有充分考虑到不同偏移距多次波的发育情况是有明显差异的，通常在近偏移距，多次波发育较强，在远偏移距，多次波发育较弱，因此本发明提出一种针对近-中-远不同偏移距的自适
