Sentinel-1 Polarimetry

There are a lot of tools for quad pol data but this data is not free. Can we have more tools for Sentinel-1?

Currently, it’s only planned to have the H-Alpha dual pol decomposition and Wishart classifier. You could have a look at PolSARPro for further polarimetric tools. Are there any in particular you had in mind?

It would be nice to have possibility to calculate Shannon Entropy

The H in H-Alpha is Shannon Entropy

can I use snap to operate dual-pol deposition to generate H and alpha? now just the unsupervised classification of dual-pol could use?
