Separating Multiples by Independent Component Analysis Method
Shunli Gao · Journal of Tongji University · 2013
The independent component analysis(ICA) for separating multiples is combined with the inverse scattering series(ISS) for predicting multiples to suppress surface-related multiples.Multiples predicted by ISS and raw seismic records make up several observation components,and ICA is applied to separating multiples from the raw seismic records.Tests on synthetic data by convolution and finite-difference modeling show the advantages of ICA in multiples separation even mismatching in amplitude between the predicted multiples and raw seismic data.But there are uncertainties in multiples separation by ICA in case of low signal-to-noise ratio of raw seismic data.
