SARPROZ ©

Yuxiao is going to answer you soon.

My only comment is: are you using the most recent Sarproz version?

Using the “single interferogram processing” module you can implement all options you like…
process the interferogram, plot it, geocode it
use it to make all experiments you like

Ivana,
+/- 3*sigma is an operation that has nothing to do with this quantity.
As previously stated, this quantity is not calibrated and it should be simply considered as a measure of the curvature (how wide) is the peak. But again, the value is not much meaningful by itself alone, it’s useful when compared with that of an other target.
Nobody ever…[Read more]

The basic ideas of Sarproz were firstly conceived during my phd thesis in the years 2003-2005 (check my thesis on Amazon or the urban target recognition paper). At that time I was using ERS and I calibrated the dataset with some corner reflectors. Since then, the calibration constant has been left in the code, and it is used when you process…[Read more]

The master is chosen in the barycenter of the distribution of normal/temporal baselines.
If you are mixing multiple polarizations, the sw will take a master among images at the highest resolution.
Registration is carried out by cross-correlating patches of images.
Then a polynomial model is fitted in the estimated shifts considering their…[Read more]

we found out that the timing of the image was decreasing.
new pcodes are already available online with the fixed version

is the image flipped? are you using the most recent updated version of sarproz?

upload on e.g. wetransfer and paste a link

right, for some reasons I forgot to answer.
Well, the easiest way for you to select manually points is to create manually a mask file.
You can do it in the following way:
– type fast in the matlab command prompt
– create vectors of samples and lines of the points you want to analyze:
Svet=[ … ]; Lvet=[ … ];
– create a matlab sparse matrix:…[Read more]

Images are equalized via a simple normalization process.
You need it to perform statistics on amplitude time series.
The unit of amplitude is volt. But its value is useful only if compared to other values, not in an absolute way.
If you could calibrate it by knowing the amplitude of a reference corner reflector,
you could derive the RCS of targets…[Read more]

First of all,
can you update the software version?
You do it through the manage version module, in the dataset selection window.
Then try again and if the problem persists, can you send us a link for downloading your LED file?

I am afraid we need to check the data together
Can we talk on skype?

Thanks Ivana,
it has already been corrected in the pcodes version
we’ll upload today also the compiled ones

If you want to get it working, please read the messages given by the sw.
The sw always tells you what’s going on and whether anything is wrong.
In case of unexpected errors, all error details are saved in a .mat file.
If you want to get assistance, zip .mat and .log files and attach them here.
If no errors occurred, just zip and attach the .log file here.

Ivana,
first of all, a general comment: you have all needed tools to investigate your problem…!!
You can plot the DEM in geographic coordinates, and you know you should expect 4 black crosses that give you an idea about where is the footprint of your data w.r.t. the DEM. I do not see them in the picture above, and this should be a first sign…[Read more]

If you don’t understand Matlab,
then maybe not much to do…

I try to give you a hint to read the message shown by disp_err in any case..:
The list of files tells you the inter-dependency between them (the sequence of calls) at the moment the error occurred.
The list starts from the upper level.
You were in Site Processing (“analisi_sito”), you…[Read more]

Hi Ivana,
the error there is related to the SLC data module (by the way, to check it, you just need to type “disp_err” at the matlab command prompt -if you work with the compiled version, just copy the lasterror.mat in the working directory of any Matlab session [disp_err.p works independently and even without license]-).
Sometimes it may look…[Read more]
