My computer is a windowins system, I installed Cywin64 software to call Snaphu V2.0.4 software for phase unwinding, the output is always not right.The first photo is before the processing, the second photo is after the processing.
Hi,
You don’t need Cywin64, you can install Snaphu thanks to SNAP’s>Tools>Plugin
And good instructions about how to use it are here: https://step.esa.int/docs/tutorials/S1TBX%20TOPSAR%20Interferometry%20with%20Sentinel-1%20Tutorial_v2.pdf
