Polarization VV and VH


I have one question, it may sound silly, but I believe no silly question :smiley:

So, I analysed the backscattter value of Sentinel 1 (VV and VH pol) for palms in dry and wet season. I would like to see how the backscatter value behaves in those season. Accordinngly, I would like to indicate which polarisation is better for discriminating palms in different season. I found that VH pol has higher backscatter value on wet but VV has no signifcant effect whether in dry or wet.

So, according to you, can I say that VH polarisation is better because it shows the significant effect due to moisture content or the VV pol is then better because it remains stable through out the seasonal change?
I am very new in radar interpretation.
Would be nice to listen some answers from the forum.
Thank you

We could tale a look at the following slide as reference point to C band, backscatters from canopy, the palm in the case scenario, the backscatters pulses return to the antenna from within the canopy, thatโ€™s mean volume reflection, but, in case of palm letโ€™s ask good question (What is the density of the canopy?) and other good question (Is there any possibility of get scatters back from the ground?)

Answering the aforementioned both questions, would lead us to the following, Comparison of VH to VV polarization,

VH could be better than VV under two circumstances, the first one is the calm wind, rainy weather or the scene aftermath rainy day,

But in the following, the opposite result, could be found,

That leads to an important point, The general behavior of polarization could be changed according to the specific conditions, the target represents the most important variable.
