Resource Overview
This MATLAB-based implementation provides source code for seismic wavefield continuation and migration positioning. Seismic migration is a critical step in seismic data processing, using algorithms like Kirchhoff migration or wave-equation migration to simulate wave propagation and reposition reflections to their original subsurface locations through velocity model-based depth conversion.
Detailed Documentation
Based on the MATLAB platform, we have developed source code for seismic wavefield continuation and migration positioning. Seismic migration is an indispensable step in seismic data processing as it enables better interpretation of subsurface structures. The program implements wave propagation simulation using finite-difference methods or spectral techniques, modeling how seismic waves travel through underground formations. Through migration algorithms that incorporate velocity models and imaging conditions, the processed data is accurately repositioned to its original reflection points, ensuring data reliability for structural analysis. Key functions include wavefield extrapolation, depth migration kernels, and coordinate transformation modules. This source code assists seismologists in analyzing subsurface geometries and advancing seismic research through reproducible computational methods.
