InSAR processing of Sentinel-1 using ROI_PAC
This code makes ROI_PAC capable of handling Sentinel-1 TOPS data for interferometry.
The method is described in the following paper.
Grandin, R., 2015. Interferometric processing of SLC Sentinel-1 TOPS data. In Proceedings of the European Space Agency, SP-371. FRINGE 2015, 23-27 March 2015, Frascati (Rome), Italy. The paper can be found here. Please cite the above paper if you used this program in your scientific work.
You will need to install a few python packages (mpmath, gdal, ...), to re-compile a few ROI_PAC routines and to add a few Perl scripts to your $MY_SCR folder. Everything is explained in the README file.
You will need to write a parameter file that tells the processor where your Sentinel-1 data are, where your DEM is. You can feed as many Sentinel-1 images as you want, as long as they are contiguous along the track and acquired on the same pass. A fine DEM is needed (30 m posting or better).
