Dear,
I want to understand the full demonstration of this paper: Angular correction of the radiometric slope of Sentinel-1. Could someone give me a hand? Fig1 and Eq. 5 are not understandable because there is no clear demonstration of how equation 5 is obtained, nor the angles involved. A geometric clarification on the various angles would be very helpful to me.
Someone if you have any reference or if you can explain in detail I will be very grateful.
I am applying this correction to S1 images for mapping burned areas but if I can’t understand the rationale I’d rather not continue, I’m one of those who likes to understand the background and then move on.
Thanks in advance.
