image - Free radar (SAR) satellite data

I'm looking for free (non-commercial use) sources of radar (SAR) satellite imagery. Does anyone know of sources?

Answer

• You can get Sentinel-1 data from scihub.esa. Requires only registration (And most likely, non-commercial use). As Sentinel-1 has just become operational the archive is not very extensive but should grow quite quickly.



• You can set request data-access propospal on Alaska Satellite Facility. Some data open access. For ALOS-PALSAR you must be a resident of the United States to receive approval for data access.


• You can get data from UNAVCO SAR data archive.


• And you can get data from earth.esa.int. To access the data, you must provide a project. To preview scenes, use EOLi esa. ENVISAT ASAR the best option.
