Phase Unwrapping Calculation


I work with Snap 2.0.2 and 32 GB of ram I have a question regarding the Phase unwrapping. How is the
Phase unwrapping being calculated by snaphu?

I exported the complex data plus Intensity, Phase, TopoPhase and the coherence with Snap
by clicking “Snaphu export” in the radar section.

How does Snaphu calculate the Phase (unwrapped)?

What I got is:

· Phase (wrapped) +/- Topo_Phase +/- Phase © = Phase (unwrapped)
· Is this the correct equation?
· Is there any term missing in this equation above?
· What is the term “Phase ©” all about?

Please let me know, because the manual of Snaphu doesn’t give me a full insight to this.

Kind regards
