This is actually the first time I've seen the SAR algorithm explained. Every SAR project I've seen glosses over this part.

Wonder if anyone else has seen more resources on this? Going to try to digest the linked paper.. https://topex.ucsd.edu/rs/sar_summary.pdf

And in the end it seems you can bypass a lot of the position problems with autofocusing! First time seeing this part too :))
