Extracting SAR level0 data from file

[adam32]

Hello
I am working on SAR interference mitigation. I need to load a level0 (raw) SAR data in Matlab for further processing. So I downloaded some level0 datasets, including ERS and RADARSAT1 data. When I extract the downloaded archive file, there are multiple files within it, including ,metadata, .ldr and .raw files.
I don't know how to extract the SAR signal from the .raw file and load it in Matlab.
So if there is any method or tool or any procedure to extract the level0 data from the .raw file and access it in Matlab, please let me know about it
Thank you so much

ERS and RADARSAT-1 data are in CEOS format. I hope these document will provide information you find helpful:

If you have access to Matlab's Radar Toolbox, you can follow this tutorial for working with ERS data, and should work similarly for RADARSAT-1:
