White ripple band appears on the image of S-1 data during preprocessing

White ripple band appears on the image of S-1 data during preprocessing,how to repair the image for this problemh?

That looks like Radio Frequency Interference (RFI) from other C-band emitters, for example ground-based radars.

In the latest S-1 IPF update RFI is flagged/mitigated when possible.

Sentinel-1 Using the RFI annotations - Sentinel Online (copernicus.eu)

Thank you very much, it is very helpful to me.Where can I download this tool or feature?

It is available in all products processed with Sentinel-1 Instrument Processing Facility (IPF) v3.4.0 or later.


Is this process?Always can’t go through :sob:


Use GRDH data is submitted to the other errors :sob:

You do not need to do anything, the correction, if available, is already applied in the product. Data processed with earlier IPF versions (before v3.4) needs to be reprocessed by the PDGS in order for users to benefit.

Okay, thank you! I will update the snap and try again.

Hello, how can I reprocess the earlier data with PDGS(such as 3.31),in SNAP?
I didn’t find this module(PDGS) in snap? thank you!
