we discussed in here to what extent dual pol entropy/alpha decompositions make sense: H-Alpha Plane Problems - #34 by ABraun
To my understanding, it is a technically possible, but kind of counterproductive because it disregards the actual idea of quad-pol decompositions.
You can follow along steps 1-3 to prepare the data for the processing: Calibration in PolSARpro problem - #28 by Aashishm
Or in short form: PolSARpro_v5.0-problem with main input directory - #2 by ABraun

Also, the steps are discussed here: PolSARpro v.5.1 unzip problem
The DualPol Alpha/Entropy classification is also featured in SNAP, by the way.
PolSARpro offers an immense multitude of polarimetric functions and modules, far more than SNAP, but you have to know at least what you want. Polarimetry has a strong mathematical and theoretical component, it is far more than executing modules and getting results. This makes it kind of hard to access.
You can start with the PolSARap Showcases (under Education)
