If you are pertaining to a semi-automated workflow using SNAP-StaMPS (StaMPS is a Matlab-based time-series InSAR processing tool), you can visit the STEP Forum. The forum provides rich discussions about all SAR- and InSAR-related topics. Here is the link. https://forum.step.esa.int/
I suggest using the search bar of the forum for any topic of interest or issues you encounter during installations of pertinent software packages and later, processing of SAR data.
I hope you will also be fine. For the first and foremost, as you now, numerous papers have been published about this subject and you can use them as soon as possible. Furthermore, I deduce that if you want new sources, you can study the following articles. I wish the best for you.
