Reverse time migration (RTM) is more applicable for the imaging of complex structures than one-way wave-equation migration and Kirchhoff integral migration.

逆时偏移比单程波波动方程偏移和克希霍夫积分偏移更适于复杂构造成像。

In Kirchhoff migration, this is done by using the Kirchhoff integral representation of a field at a given point as a (weighted) superposition of waves propagating from adjacent points and times.

克希霍夫偏移中，反传播的处理就是把特定点的波场克希霍夫积分表达式作为从邻近点在邻近时间传播来的波的(加权)叠加。
