Is there any Back-scattering intensity library availability for different crops

hello sir,

I’m interested to do different crops identification using SENTINEL 1 data,but the thing is it is difficult for me to identify different crops using the back-scattering intensity values,sir can you please help me in the process of identification of different crops based on back-scattering intensity.

Sir is there any availability of BACK-SCATTERING intensity LIBRARY, like for Optical data we can get SPECTRAL LIBRARY for different crops,so that it will be easy to identify different crops for optical data.

sir I’m requesting you to please help me in the SENTINEL 1 data crops identification process.

many thanks in advance.
