Global 25 m Resolution PALSAR-2/PALSAR Mosaic

Microwave Toolbox Polarimetry

Hi,
I am trying to use the Global 25 m Resolution PALSAR-2/PALSAR Mosaic data for my work where I found the images having really high pixel values. So these images have the backscatter coefficient as information or just the DN values and we have to convert them to gamma naught using the formula:

š›¾0 = 10 log10āŒ©š·š‘2āŒŖ + CF

Thank you very much.

Yes, these are uncalibrated digital numbers
You have to apply this equation to get the db scaled Sigma0 values.
