Orbit based coregistration
Added by Virginia Brancato over 6 years ago
Hi Gamma Users,
a very quick question. Is it possible to do the coregistration of two SLCs (any SAR sensor) solely based on the orbit state vectors? Is there any tool in Gamma allowing to do that?
If I am not wrong, there should be something for Sentinel but what about other sensors (e.g. TerraSAR-X)?
Thanks a lot for your help.

Hello,
Yes there is a way. The program rdc_trans generates a lookup table to resample one MLI image into the geometry of another using orbital state vectors and
other SLC parameters. Then you can use the program SLC_interp_lt to resample one SLC into the geometry of the reference SLC using the lookup table. The lookup table can be refined used offset measurements between the SLC images. The script SLC_resamp_lt_all (See the html documentation for SLC_resamp_lt_all) is an example of how this can be done.
