Sentinel-1 Processing Steps?


#1

Hello,

can anyone tell me which pre-processing steps are applied on the Sentinel-1 products?

As they are provided in gamma nought, at least calibration must be involved. In the documentation I saw that thermal noise is removed as well (https://sentinel-hub.com/develop/documentation/eo_products/Sentinel1EOproducts). What else? In which order? With which parameters?

I’m trying to figure out if the Sentinel Hub can save me my processing routine or at least parts of it…

Thanks

Hi,
Correct, calibration and thermal noise reduction are applied. This is done first and at the same time. After that the geolocation processing follows, either orthorectified or non-orthorectified, depending on you settings.
Note that as of this writing speckle filtering and terrain flattening are not supported.
I hope this helps
