Slant Range to Ground Range


I am working on an ALOSPALSAR2 SLC product. My confusion is that "Does the Range Doppler Terrain Correction change slant range to Ground range "?

I would greatly appreciate any help. Thank you in advance!

The Slant To Ground Range module just corrects your image domain from temporal (slant) to spatial (ground).

The Range Doppler Terrain Correction module does this as well but simultaneously geocodes your image to a selected coordinate system.
