Abstract:Geophysical inversion is one of the subjects which the worldwide geophysicists and applied mathematicians are interested in at present,In this paper,approximate 2D wave equation is used to describe how seismic wave travels in horizontal layered medium,In the case of given common shotpoint record,the Fourier transform of wave equation can bring integral equation along characteristic line;then,impedance and velocity parameters can be derived using new given difference scheme,The trial computation of a horizontal layered model proves this method feasible in both theory and practice,In noisefree case,its accuracy is quite good.
