I am new to SAR and have some questions.
I want to incorporate optical and radar to do a very dense time series of land use change since the early 1990s. I have to incorporate SAR because the study area is a tropical region with lots of cloud cover.
My goal is to come up with a value from 0-1 that represents level of vegetation using SAR, so I can use it in a time series alongside optical data (NDMI).
The land use change I am most interested are fields opened up (less than 17 hectares) within intact rainforest. I am thinking of using HV polarization because it is more sensitive to volume scattering and has high contrast between low vegetation and high vegetation, which may make it nice for field identification.
