Units of stokes parameters

Dear all,

I am relatively new in the SAR community and I have a basic question which seems hard to find an answer on. I used the CP Stokes parameters operator to derive Stokes parameters after generating the C2 matrix from VV+VH S1 SLC images. When I open the image of the first stokes parameter it indicates a unit of Intensity. Does this mean the units are W/m2 or is it W/(m2*sr) or a completely different unit and why?

Thank you so much in advance for answering.
