%X In this article, a higher order symplectic scheme approximation to the complex exponential function in the one-way wave equation is used in the seismic migration algorithm. The symplectic method is compared with the two-step method developed by Clearbout and several non-symplectic methods. The result shows that the symplectic scheme has an higher accuracy. The impulse response on even velocity model and simple lateral variable velocity model shows that the symplectic method can decrease the frequency dispersion and adapt to the lateral velocity variation. Results on Marmousi model and field data show that the method can also be used in seismic migration, especially for the deeper section.
