You can find a tutorial here for Sentinel 1 :
As falahfakhri said, you don’t need to deburst ENVISAT, it’s a scansar not a topsar.
For snaphu it’s a mess using a docker on windows especially beacause you can run snaphu easily whith a VM. In my opinion …
Dear Mr. Veci and Haouet, dear Dr. Fakhri,
thank you so much for the answers. It is always a big deal to get some help at the start of your career, especially after a year off because of a serious health problem.
As I see there are no Orbit Precise Data for ENVISAT ASAR. The last ones (Delft) are dated back to 2014 and are ERS Data. That means that we have a long, long coregistration/IFM-Saturday with SNAP ahead of us. Or am I missing something?
I have already studied the links that you sent me. Thank you again so much.
I personally managed to install and run SNAPHU on windows with no problem.
You can compile it with cygwin. If you are interested let me know.
I also did it for STAMPS but I can’t say if it runs correctly, yet.
I have a little problem trying to compile snaphu with cygwin. I found these instructions
I have a little problem trying to compile snaphu with cygwin. I found these instructions
Go to /usr/local/ Path: cd /usr/local/
Create directory man and man1: mkdir man man/man1
Go to local directory: cd /snaphu-v1.4.2/src
Compile SNAPHU: make install , automatic start of Makefile!
Open SNAPHU help: snaphu.exe
but the third step fails. And this makes sense, since there is neither c nor d in the file usr/local. Do you have any ideas?
Thank you.
this is a bit tricky in cygwin.
For example, if your downloaded snaphu files are located in
C:\Temp\snaphu-v1.4.2\src
you need
cd /cygdrive/c/temp/snaphu-v1.4.2/src
Type ls to see if you are in the right directory.
Wait, it did work. But now the command 'make install" does not work.
did you download and extract the snaphu files from here?
https://web.stanford.edu/group/radar/softwareandlinks/sw/snaphu/
https://web.stanford.edu/group/radar/softwareandlinks/sw/snaphu/snaphu-v1.4.2.tar.gz
The commands are not correct at all. Now I am in the right file and I am advised to type make install, but this does not work either.
make command not found
make is located in cygwin64\bin and should be recognized by the cygwin console.
Are you sure you installed cygwin correctly?
No. Installation was incomplete.
Package: _/libfontconfig-common
fontconfig_dtd.sh exit code 2
then please uninstall everything related to cygwin and download this package
https://cygwin.com/setup-x86.exe (Windows 32 bit)
https://cygwin.com/setup-x86_64.exe (Windows 64 bit)
Alternatively, you can install GIT for windows which also features all UNIX tools. However, I’m not experienced with it.

Hi Andreas, thank you very much for your SNAPHU tutorial.
After compiling SNAPHU in CYGWIN, i copy SNAPHU.EXE to different directory. I can not run SNAPHU.EXE in Windows Command Prompt.
After a research, i found this from: https://www.samkear.com/networking/how-to-compile-iperf-for-windows-using-cygwin
You will also need the following DLL files found in C:\cygwin\bin.
cygwin1.dll
cyggcc_s-1.dll
cygstdc+±6.dll
Copy the three DLL files and iperf.exe somewhere on your system that is in your path like c:\windows\system32 for example. You can then run iperf directly from a command prompt.
This will may be help for some questions.
After copying these DLL’s, SNAPHU.EXE run at Windows Command Prompt…
thank you for the solution.
I however still think that adding the cygwin directory to the system’s path variables should have the same effect.
Hi Falahfakhri,
I have work a lot with radar images, with the amplitude and in some cases polarimetric parameters, however, I am new in interferometry, and specially in PSI/SBAS…
I would like to process some ERS images to PSI.
So how shoul I do?
Thanks a lot!
Hi @falahfakhri
Many thanks for your answer.
I will try the steps that you propose.
A last doubt, what about the topo phase removal? I have to apply it after the interferograms formation?
Many thanks again.
