The relationship between scattering series fields

Scattering theory plays an important role in the seismic data processing and other fields. Recently, the method of inverse scattering series has already been used to remove free surface multiples and to attenuate internal multiples, which is significant to seismic data processing. The paper deduced the theoretic model of scattering series in detail. And the authors discussed the relationship between scattering and multiples by studying the properties of forward scattering series and pointed out the relationship between scattering and primaries, multiples. All these are used to the inverse scattering method. At the same time, the paper discussed the difference between inverse scattering series imaging and Born approximation imaging. The results show that born approximation imaging is only useful to small perturbation, and to great perturbation it will cause great error, but inverse scattering series imaging can obtain the accurate model parameters.
