摘要

利用三维非均匀介质中的波动方程 ,进行振幅保真波场偏移算子分解 ,得到用于真振幅偏移的单程波方程 .经过数学推理 ,导出裂步Fourier法真振幅偏移和Fourier有限差分法真振幅偏移的算子方程 ,并给出其具体的实现过程 .
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.
