摘要：
我们开发了一种用傅里叶积分算子表示的反时迁移方法，其规范关系为图。通过相空间的双亲分解，我们利用波包求解具有边界源和齐次初始条件的波动方程。在此基础上，我们开发了从散射数据边界进行反时延续和RTM迁移的数值程序。这些算法源自我们最近为离散近似计算傅里叶积分算子作用所开发的算法，并继承了其概念和数值特性。
英文摘要：
We develop a representation of reverse-time migration in terms of Fourier integral operators the canonical relations of which are graphs. Through the dyadic parabolic decomposition of phase space, we obtain the solution of the wave equation with a boundary source and homogeneous initial conditions using wave packets. On this basis, we develop a numerical procedure for the reverse time continuation from the boundary of scattering data and for RTM migration. The algorithms are derived from those we recently developed for the discrete approximate evaluation of the action of Fourier integral operators and inherit from their conceptual and numerical properties.
