Three current migration methods derived from the wave-equation model and based on approximations by Fourier series, finite-differences, and a combination of both (mixed method) are reviewed. Each method is examined in the context of horizontally layered media, where the velocity of wave propagation varies with depth alone. It is shown how, under such conditions, the special properties of the linear equations obtained from finite-difference and mixed approximations can be exploited for… CONTINUE READING
