逆时偏移(RTM)一般采用零滞后互相关成像条件,要求在同一时间步长上知道源波场和接收波场。但是,接收器波场是以时间反转的顺序计算的,这与
Reverse time migration (RTM) generally uses the zero-lag crosscorrelation imaging condition, requiring the source and receiver wavefields to be known at the same time step. However, the receiver wavefield is calculated in time-reversed order, opposite to
