The Sentinel-1 SM Toolbox is a set of Matlab functions to easly compute the Sentinel-1 A/B interferograms in StripMap mode. The objective is to have a simplest file of parameters to run Doris 5.0.
The Toolbox contains:
- computation_Sentinel_SM.m: main function to run the interferogram computation
- read_data_Sentinel_SM.m: function to read the S1 data and the orbit files, to create the file for Doris 5.0
- detection_orbit_files.m: function to detect the good orbit file in one directory
- readSent1Data.m: function to read the SLC images by Louis-Philippe Rousseau
- getTIFFinfo.m: function to read the tiff informations by Louis-Philippe Rousseau
- cmap_sar.csv: colormap for the interfergrams
- sar.m colormap for the interfergrams (in the Matlab format)
- card_raw.input: input card to run the computation_Sentinel_SM.m function.
The other requirements:
- xml2struct.m
- ToolBox Envi for Matlab to create the UTM products (optionnal)
- ToolBox Mapping of Matlab to create the DEM geometry products (optionnal)
- The readSent1Data.m function to read the SLC images by Louis-Philippe Rousseau
- The getTIFFinfo.m function to read the tiff informations by Louis-Philippe Rousseau
