As we know, SNAP give a selection about removing thermal noise from Sentinel-1 imagery. However, I don’t know whether noise removal is a must by ourselves after a step in SNAP S-1 Thermal Noise Removal .
I think the results still have serious thermal contaminate after a thermal noise removal in SNAP, as following example, I have done removal but the noise is obvious.
Sorry, the image shown before is HV-pol image rather than HH-pol one. Banding effect noise is not obvious in HH-pol, this phenomenon is a problem for HV-pol images . Some papers about sea ice classification will only do incidence correction for HH-pol and thermal noise removal for HV-pol imagery.
Yes, you are right. But the picture I given is dB value. In dB image, the phenomenon is more obvious than your result. But I don’t know the reason for your question.Sorry.
Hello qglaude,
Did you just figure out how to solve these corrections using snap in a cross polarized (HV) channel???
If yes, can you please elaborate on how you went ahead
