periz replied to the topic velocity standard deviations in the forum Sarproz Forum 8 years, 10 months ago
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] -

Hi Daniele,
thank you very much for the explanation and also for the implementation.
Can you also please let me know how is the periodogram peak width defined? If e.g. the width of 90% of the peak coherence. Just to consider if really plus minus three sigma_vel are the “limits” of the velocity estimation as the values really look quite…[Read more]

periz replied to the topic using RCS PSC threshold in the forum Sarproz Forum 8 years, 10 months ago
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]

Did anyone know about the Radar Cross Section Threshold? What is the typical value for reasonable PSC? I am using TSX 3 meter SM data

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] -

Hi,
I want to know that what’s the method of SARPROZ choose master image? Can you tell me that? Does it based on temporal baseline or spatial baseline,or other method? Is there has some literature about how SARPROZ choose master image?
And SARPROZ use which method on image Registration? Is there has some literature about SARPROZ‘s method?Thank you!

Thank you Yuxiao,
but today (with the 06-Oct version) I get a similar/same error.
(will try the other stuff later. Before, I threw the images with only partial overlap away, but now I do not. The area of interest is covered, but I get these problems…)

Yuxiao replied to the topic Second Sample/Line value MUST BE GREATER than the first!! in the forum Sarproz Forum 8 years, 11 months ago
To conclude this thread, the newest version of sarproz should solve this issue.
Thanks!

Hi Ivana,
We’ve uploaded a new version of pcodes that solves this issue.
By the way, I have tested the new version of pcodes on your testing site, and it should also solve the previous problems you’ve mentioned in the other thread.
Please let me know!
Thanks,
Yuxiao

we found out that the timing of the image was decreasing.
new pcodes are already available online with the fixed version -
matusbakon replied to the topic RADARSAT-2 geocoding error in the forum Sarproz Forum 8 years, 11 months ago
yes, the image is flipped, my version is 19-Sep-2015 09:47:45 due to version manager the newest one

periz replied to the topic RADARSAT-2 geocoding error in the forum Sarproz Forum 8 years, 11 months ago
is the image flipped? are you using the most recent updated version of sarproz?
