摘要
We analyzed the amplitudes produced by shot-record migration by one-way wavefield extrapolation. By comparing these amplitudes with those produced by true amplitude Kirchhoff migration, we show the amplitude and phase errors that come from a standard implementation of migration by one-way wavefield extrapolation.
