Imaging using compressive sensing
Robert G. Clapp
Abstract:
Constructing 3-D angle gathers is quickly becoming the computational bottleneck in Reverse Time
Migration (RTM). Both the expansion in volume size (120-900x) and the cost of cross-correlating
wavefields greatly increase the cost of RTM. Both the storage and computational cost can
be greatly reduced by reformulating the imaging process as a compressive sensing
problem. Preliminary results show that this approach holds promise but finding
an acceptable L-1 inversion approach is still problematic.
