A new method to eliminate first order internal multiples for a normal incidence plane wave on a 1D earth

摘要

A new method to remove internal multiples has been derived under 1D normal incidence. This new method is a step further from the inverse scattering series(ISS) internal-multiple atten-uator(IMA) to an eliminator under 1D normal incidence. In the procedure of the method, it constructs the reflection coefficients in order to remove the extra transmission coefficients of the events and then constructs a new function based on the reflection coefficients. This method may be relevant and provide value when primaries and internal multiples interfere with each other in both on-shore and off-shore data under near 1D circumstances. This method does not seek higher order terms in the ISS to construct an algorithm that eliminate first order internal multiples generated by all reflectors.
