Engineering Contradiction Analysis
1Productivity
If traditional separate source and receiver wavefield extrapolation methods are used, then processing accuracy is maintained, but computational time and processing costs increase significantly
Solution Approach 1:
The patent combines separate source wavefield and receiver wavefield extrapolation operations into a single integrated wavefield extrapolation step. By merging these two distinct processing operations into one unified operation that simultaneously handles both source and receiver wavefields, the computational time is reduced while maintaining the accuracy of subsurface feature characterization.
2Productivity
If advanced distributed supercomputer systems are employed, then processing capacity increases, but costs and bandwidth requirements increase
Solution Approach 1:
By merging separate wavefield extrapolation operations into a single integrated operation, the patent reduces the overall computational workload and processing requirements. This consolidation decreases the need for high-cost distributed supercomputer systems and reduces bandwidth demands while still achieving the necessary processing capacity for accurate subsurface imaging.
3Measurement precision
If separate wavefield extrapolation operations are performed for source and receiver, then processing precision is maintained, but device complexity increases
Solution Approach 1:
The patent integrates separate source and receiver wavefield extrapolation operations into a single unified operation that processes both wavefields simultaneously. This merging reduces the complexity of the processing system by eliminating the need for multiple separate operational sequences while maintaining the precision required for accurate subsurface feature characterization through the combined operation.

AI summary
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.
