I think you need to perform some indices and image classification

Well this can be performe using SAR image cohernce and polarization (q,i).

Masoom Reza This can be done using Quad Pol Microwave data. Use Decomposition techniques.

SAR data being sensitive to surface roughness of the target, is likely to give lowest backscatter at water(Specular reflection). due to high di electric constant of ice, and roughness of ice surface, ice is likely to give strong backscatter due to scattering at most of microwave region. distinguishing between different ice forms would be more challenging and needs more detailed study and is more dependent on frequency used.

Preet Lal Thank you for your answer. Can you please tell me which decomposition will be helpful, if i use sentinel 1 data.

Thanks for your answer. Please suggest me some processing techniques.

I am using sentinel 1 data.

Masoom Reza the processing technique for ice or snow classification depends upon the user, but you have to perform basic processing S-1 data. Attached are documents with pre-processing steps of SAR data in SNAP toolbox.

May be this link will help you https://sentinel.esa.int/web/sentinel/user-guides/sentinel-1-sar/applications/mapping-applications-s1-modes .

Gomal Amin Thank You for your answer. This is what I was looking for.

Thank You
