Yes. In fact, all the pixels displayed correspond to one corner reflector. I am playing with the data to see if the reflectors are really visible, the interpolation of the position and phase will be the next step for me to try.
But the problematic pixel is the one I expect to be the center, with the highest intensity. I did not meet this problem…[Read more]

Dear Prof.Daniele
I got results from CSV file, but I cant find residual Height value.
What mean of “HEIGHT WRT DEM and SIGMA HEIGHT” in CSV column?
If Residual Height = Height – External DEM, Could I say that Residual Height = HEIGHT – HEIGHT WRT DEM (based on CSV column)Besides that, in SARPROZ, how I can generated and get data “phase r…[Read more]

you insist willing to include dependent pixels, and this is a clear example that dependent pixels create only problems, without increasing a single little bit the information that you can extract
in that plot you have 2 scatterers, one covering 3 pixels, the other one covering 2 pixels
the height you estimate is fake, because it’s pixel…[Read more] -

Hello,
what does this error mean?I (repeatedly, consistently) cannot get information/timeseries for this point… is the reason that the two points are too close to each other?
Thank you,

Yes, the .off file is present and looks reasonably.
And slave image is also in the EXT folder, except for the fact that it is not VV, but HH, and the corresponding jpg looks reasonably, similar to the master.
By the way (the processing is not important, I am doing it just to check and see), I could not open the site processing (did you see it…[Read more]

Hi Ivana,
by looking at the log files, I would suggest the following:
Checking in /EXT folder the file 20150123_20150324_init.off and check if there is anything written inside.
It would also be helpful to check the intensity of both the master image and slave image. the master will be in FITTED folder as the name 20150213.jpg. The slave image…[Read more]

Hi Ivana,
I can’t see your log in the forum… Can you find another way to pass the log file?
thanks,

periz replied to the topic SAR coordinates computation in the forum Sarproz Forum 9 years, 6 months ago
type “fast” in Matlab
and then use the following expression
[Rg,Az]=geo2SAR(lat,lon,h,el,Master,handles.SiteParam.DirSite);
el=1 corresponds to WGS84
otherwise input a string like GRS80 or the ellipsoid you needto extract phase/amp values the easiest way is to use the small area.
when you load a small area, complex numbers are accessible in the…[Read more] -

Hello Yuxiao,
just for sure, I am reporting failed coregistration (for 1 image) on different scene set. I cannot find any reason (error) for this. And the error does not let me go further.
Thank you, Ivana

Hello,
I would like to ask if there is any (direct) possibility to compute SAR coordinates (let’s say with the precision of 10-20 pixels) on the basis of known lat, lon. And then, if it is possible to grab out the phase/reflectivity values of (few) selected pixels.
Thank you, Ivana

Hello Yuxiao,
OK, trying to attach the logfile (long).
the image with the phase jump is 20141223.
and the images with wrong coherence (at the North) are 20150820-20150901, 20150703-20150715, 20150808-20150901, 20150727-20150808, 20150715-20150727.
regarding the area: the center is now (if I remember well, is it possible to get the values…[Read more]

Hi Ivana,
Recent days I am working on killing the bugs that are possibly occurred because of partial overlap images. In the next few days a new version should be released and it should work better with those partial overlapped images.
Can you provide the log file of geocoding all interferograms and what the error is? So we can look into detail…[Read more]

Hi Matus,
I am still looking into your results and logs, but I reply here what I’ve finished looking and I will keep on investigating and reply you the rest.
1. Co-registration-error: Sorry, this error was due to a bug in the code that deleted the SLC file so that the file for coregistration refinement is missing. I will kill this bug for the…[Read more]

Hello,
sorry for my long pause, I was out.
Now I am trying the processing again, with the compiled version of Aug 31st (as the update function does not work for me in the matlab version).
I decided to delete those problematic images, as they were problematic due to only partial overlap with the others in the AOI. The process of selecting the…[Read more]

finally, i get some promisingly looking set of images and interferograms, but also:
1) corregistration refinement error (applied experimentally),
2) interferograms plotted through Small Area Processing differs when “View SLC” and “Read and Plot Interfs” functions are used,
and can be seen in attached zip (second folder with time-ordered print…[Read more] - Load More
