For practicing spotlight processing, i am looking for I/Q baseband signal from a SAR airborne or spaceborne system. In my research I have only found processed image from :
- eoweb geoportal https://eoweb.dlr.de/egp/
- Airbus Terrasar X https://www.intelligence-airbusds.com/imagery/constellation/
Could anyone give me a link for raw I/Q signal (and associated metadata)?
Thanks a lot
