I use NEST software From ESA "https://earth.esa.int/web/guest/home;jsessionid=9944AA626F7C6F2942DD3DC2027427BC.eodisp-prod4040"
for DInSAR processing but I encountered some problems in Phase Unwrapping of the produced interferograms.
These problems represented in installing and compiling SNAPHU "http://web.stanford.edu/group/radar/softwareandlinks/sw/snaphu/"
on Linux Ubuntu
SARSCAPE is obviously not free, unfortunately.
If you consider free software, give a try GMTSAR on Ubuntu or Mac. GMTSAR use snaphu for phase unwrapping. Someone might think using LINUX is troublesome, but GMTSAR has very good trick to make it works simplest as possible,
It has a straightforward script dealing with focusing your raw data (level 1.0) to phase unwrapping...
Dear Yusen, I am total agree with your point of view, however the default instalation of ROIPAC, does not involve the snaphu algorithm to achieve the phase unwrapping. The default algorithm or icu, sometimes may present serious difficulties to acomplish the unwrapping step(for instead for Alos Palsar data). So, in many cases is useful to install the snaphu method for ROIPAC. To avoid all these issues, GMTSAR is an excellent option!.
one of the best 2D and 3D phase unwrappers are developed by Liverppol John Moores Univesity... they are free..

im having the same problem in phase unwrapping. im using level 3 product of SLC Radarsat2, and generate InSAR using product.xml in the file. my phase image is not really good. my work stop at the unwrapping step. there is no image to select. anyone can help me?
I would recommend you to look at http://www.sarproz.com/ It has GUI, runs on all OS, and offers bunch of different functions for adaptive filtering, etc.
