    In the table, we have sigma^0 = beta^0 * sin(i_{x,y}). Is this correct? The bottom image (“Normalization areas for SAR backscatter.”) would suggest sigma^0 = beta^0 / sin(i_{x, y}).

    Hi Everyone,

    I have a question related to the probability density function of the backscatter pixels in an area considered homogenous. I’ve read that they follow a Gamma distribution, however, for Sentinel-1, I would like to know if the gamma distribution only describes homogeneous areas using Single Look Complex (SLC) products or also GRD products as delivered by GEE. Thanks in advance for any help. Liliana

    Amount of backscattered energy going back to the sensor depending on factors such as surface roughness, dielectric properties, viewing geometry etc.

    The reflected radiations of an active microwave remote sensing sensor from the Earth’s surface is the radar backscatter. It can be represented as sigma naught, beta naught, or gamma naught.
