Method and system for efficient extrapolation of a combined source-and-receiver wavefield

摘要

The current document is directed to computational systems and methods carried out by the computational systems for propagating a combined source-and-receiver wavefield from a first level to a next, second level with respect to depth, time, or another dimension. The methods and systems, to which the current document is directed, apply an efficient complex, combined-source-and-receiver-wavefield propagation operator to a complex combined-source-and-receiver wavefield in order to propagate the complex combined-source-and-receiver wavefield to the next level. Real source and receiver wavefields at the next, second level can then be extracted from the complex combined-source-and-receiver wavefield at the next level.
