2D ocean-bottom marine acquisition via jittered sampling
This application is available only in the software release for members of SINBAD consortium.
This software release includes a demonstration of the 2D time-jittered (or blended) marine acquisition scheme, and a deblending framework based on sparse inversion via L1 minimization.

Downloading & Dependencies
The code can be found in the SLIM sofware release under /applications/Acquisition/2DTimeJitteredOBS.
The code has been tested with Matlab R2012b and requires the Parallel Computing Toolbox.
This code uses the following packages, also found in the tools part of the SLIM software release.
- utilities/SPOT - object oriented framework for matrix-free linear algebra.
- utilities/pSPOT - parallel extension of SPOT.
- utilities/SegyMAT - Matlab/Octave toolbox for reading and writing SEG-Y formatted files.
- transforms/CurveLab-2.1.2-SLIM - CurveLab with SLIMs FFT Functions + other.
- solvers/SPGL1-SLIM - SLIM version of SPGl1
Running & Parallelism
All the examples and results are produced by the scripts found in this software release under applications/Acquisition/2DTimeJitteredOBS/examples/. Start matlab from applications/Acquisition/2DTimeJitteredOBS to add the appropriate paths.
To run the scripts follow the instructions in the README file enclosed with the code. The scripts can be run in serial mode but parallel mode is advised.
