Oil spill application on SNAP


Can any one help me as I’m in the final phase of my research. I have worked on oil spill detection on Snap and reached the results ( attached below ). to examine my work I have used VNA to hit an oil spill and provide the Sigma0 readings. my question how can I get the sigma0 value from the Snap of an oil spill as shown below.

With many thanks in advance!!

I think you could calibrate your image to sigma0,
