If you are a beginner you should first get used to GRD-images, as they are much simpler and faster to handle.
Yes, Sir . I am using GRD Image Product now. But When I want Thermal Noise Removal, it is error step. Can I skip this process sir?

Please look at the SAR tutorials and make sure you have installed all of the toolbox updates.
Thanks for information
After do step until Range Doppler Terrain Correction

there is no direct transfer of backscatter intensity to soil moisture. Please go through the suggestions made here: Soil moisture mapping using Sentinel-1-Data and SNAP? and here Soil moisture identification -Sentinel

Thank you for information
Can you help me to find paper or reference to calculate soil moisture with GRH product.
Regards
@johngan has given very valuable comments and literature references here: Soil moisture identification -Sentinel
Thanks for your response
you need a shapefile with attributes (moisture), import it in SNAP and use the correlative plot view.
how can i get shapefile sir?
measure soil moisture in your study area at the time when the image is acquired and locate the meastrements by a GPS device, for example.
Yes sir, I have these data
But i don’t know how to import these data to SNAP
Why not try this one - https://land.copernicus.eu/global/themes/Vegetation . This is verified product.
For SHP files import just do File->Import->VectorData->ESRI Shapefile
Hi @hriston_bg,
But when I search Surface Soil Moisture, I don’t find my study area because Spatial information is only in Europe
