Abstract:

In this paper, we derive a one way wave equation with true amplitude by the decomposition of the wavefield operator for the wave equation in a 3 D heterogeneous medium. Moreover, the Split Step Fourier(SSF) and Fourier Finite Difference(FFD) migration operators with true amplitude are derived by mathematical inference and specific steps are given.
