How to choose Speckle filter?

30 April 2020 0 5K Report

Currently, I am working with ALOS-2 PALSAR-2 data. I just want to know-

Which filter should be best for my data?

How to choose speckle filter parameters (e.g.- if I choose Lee Sigma filter, what should the number of looks, window size, sigma value, Target window size)?

Actually I want to get the radiometric terrain corrected data. In which phase I should use the speckle filtering?

Should I use speckle filtering on the ‘Beta0’ value?
