Sentinel-1 pre-processing land and water artifacts

Microwave Toolbox Problem Reports
#1

Hi,

I’m trying to pre-process a Sentinel-1 tile following the procedure presented here at

Preprocessing: Geometric and Radiometric Calibration section.

The resulting backscatter images in dB shows no water and some artifacts in land as shown in the attached screenshot.

I’m running SNAP 6.0.0

Any clue?

You can disable “exctract areas with no elevation” in the Range Doppler Terrain Correction.

Yes, I’ll try it… Thanks!
