For my research, I used the SBAS method and got “rsb” result for all interferograms. The value of “rsb” for all of them is in [-pi,+pi] but not isolated as you can see in the following figures. I am worried about the isolated property of unwrapping error is important like it’s the magnitude or not.
I do really appreciate if anybody guides me about this issue to fix. In addition, you can see the MLV result.
