An Inverse-scattering Iterative Algorithm for EM and Seismic Imaging
Based on the inverse-scattering series (ISS) theory, we presented an iterative al-gorithm which can numerically solve a higher order ISS term with all lower order ISS terms determined. This work differs from the leading order inverse scattering (LOIS) algorithm 5, 9 and the higher order scattering (HOIS) algorithm that non ISS terms are ignored in the multi-dimensional imaging. Born and WKBJ approximations are used to solve the first order term in ISS series, while the higher order terms are calculated through a band-limited discrete Fourier transform. In the iterative method, we used seismic and electromagnetic differential integral equations to reduce the costs. Our method can be used to solve seismic and electromagnetic inverse problem in geophysics and environmental engineering etc. applications.
