I am coding Range Doppler Terrain Correction Algorithm to our AirSAR data. I am mainly following these two documents however there’re many concepts that I can’t understand completely.
- A Simple and Precise Approach to Position and Velocity Estimation of Low Earth orbit Satellite
- Guide to Sentinal-1 Geocoding
I would like to ask, is there any open-source Range Doppler Terrain Correction python code available? Or if there’s another document that explains range doppler terrain correction in more detail.
You will find documentation of algorithms used in isce here - https://isce-framework.github.io/isce3/overview_geometry.html
isce2’s Orbit (https://github.com/isce-framework/isce2/blob/main/components/isceobj/Orbit/Orbit.py) data structure has a lightweight rdr2geo and geo2rdr methods that can be used for quick computations. Those equivalent fortran/ C modules implement the same equations for more heavy lifting in a parallelized fashion.
Hi, did you finish your Range Doppler Terrain Correction code? Could you please give me some hep on it?
Here are the few references that I found on internet regarding Range Doppler Terrain Correction
Thank you for your sharing. It is very instructive. Did you successfully build up your own Algorithm to AirSAR data ?
