radar data are complex, not real
so, firstly, u cannot read complex data from jpeg files, u have to read the binary files
secondly, u have to tell “leggi” that data are complex
u do this adding a flag, according to this syntax: https://www.sarproz.com/groups/sarproz-group/forum/topic/aps-processing-4/

Thank you for your reply Dr. Perissin. Could you please explain more about the steps to get the raw interferometric phase values (just topographically corrected) using the PSI method in Matlab (my data is the time series of sentinel-1 images). I had already done the PSI method in the compiled version of SARProz, but I am confused about how to…[Read more]

hi, check this about phase jumps: https://www.sarproz.com/groups/sarproz-group/forum/topic/burst-lines-on-interfereograms/#post-5462

good that you found the solution. however, I do not suggest you to use the ampl xcorr as default. we’ll try to find out a way to use it only in case of failures.

I solved the problem myself.
the problem was in coregistration.

Firstly I used “only orbits” mode for coregistration.
After analyse of Site.log the program had gave warning to that in coregistration has some thing wrong.

I tried “Ampl Xcorr” mode for coregistration and it worked match better. No warnings, No Stripe

So in future I use “Ampl…[Read more]

this is something we need to look at together. let’s plan a conf call via email please

You may set in module “Insar params” appropriate settings
Do not filter and multilook interferograms check “Flattening” and “DEM remove”
save settings
genereate interfereograms in module “interferograms protsessing”

Thank you for your reply.

I need to do topographic correction before extracting phase values. The phases should mostly contain atmospheric and displacement phases. How should I do topographic correction in Matlab?

hi,
1. if you want to work on data in the way you describe, you should use matlab.
2. to read data in sarproz (in matlab), you can use the “leggi” function https://www.sarproz.com/groups/sarproz-group/forum/topic/aps-processing-4/
3. using “leggi” you can directly read the original images and perform all what you need without caring about APS…[Read more]

Hello everybody,

I read the explanations above about the two functions get_baseline and geo2incang. My problem is that I am using the compiled version of sarproz. Could anyone give me a detialed explanation about how to use these functions to extract the incidence angles for each PS or any other pixel in the compiled version of sarproz?

Thank you

u are exporting geotiff rgb, which is in uint8 values. to export floating numbers, use geotiff 32: https://sarproz.com/manual/plot_par_mod.html

Hi Dominika,
First of all, at the moment we did not think about letting the user pass a manual reference point in the APS module in the command line mode. The sw will load the RefPoint.mat file (the default way it is usually saved), if it is working in update mode. Otherwise, it’s the sw to choose the default ref point. The reason is because in…[Read more]
