SARPROZ ©

Hello again,

Updating SARProz to version 2020 didn’t solve the problem. I also tried with both the wifi and mobile connection. Even I tested with VPN, but any of them didn’t help. It’s very emergent because I need to reprocess the sentinel-1 SLC files, and I don’t have much time. Please see attached the log file. Any help would be…[Read more]

Hello,

Here is the log file attached.

Thank you

Thank you for your reply.

After reading the forum posts, I found out that it’s a bug happening in newer MATLAB versions. Where can I update the SARProz?

Thank you for your reply.

After reading the forum posts, I found out that it’s a bug happening in newer MATLAB versions. Where can I update SARProz (pcode)?

1. please read the forum rules. you must include logs and errors or we cannot help
2. please read through the fourm https://www.sarproz.com/groups/sarproz-group/forum/topic/error-in-main/
3. please update your sarproz version.
any further topics posted without checking the forum, without uploading enough infos, without updating the software will…[Read more]

After allowing the Matlab through the firewall and restarting the computer, I solved this problem, but now I have another question. When I type fig=main in the command window, the following error raises:

Error: File: check_advpar.p Line: 75 Column: 0
Invalid syntax for calling function ‘license’ on the path. Use a valid syntax or explicitly…[Read more]

Thank you for your reply.

I tried with my mobile internet connection and a VPN, but the same problem persisted. The network that I am using is the same as the one I used before. I didn’t have the same problem before, and I have no idea what the problem is.

The Pcode version that I am using is 2019-10-02. Maybe installing a newer version would s…[Read more]

your network has problems.
change the network or use a VPN

This is a matlab MCR crash, happening while writing a file.
possible reasons:
* the disk is full
* the disk is corrupted
However, other explanations are possible as well. What’s the RAM of your system? Monitor its usage. Possible related reasons:
* RAM is over and you do not have a swap space and/or the swap space is not available/is corrupted
*…[Read more]

Hello Dear Friends,
The analysis of just 100 ascending data give a LOS displacement or vertical displacement automatically in SARPROZ. If It gives LOS, how Can I convert it into vertical displacement.

the license for windows is different from the one for linux/mac
did you do this?:
1) open a terminal (2) type ‘hostname’ (3) ping the returned name (eg: ping mycomputername)
(4) if no packets are received, add the name returned by ‘hostname’ to the file /etc/hosts

the smart function is a non parametric model, basically a time filter that smooths residuals. thermal expansion is a function of temperature, which has a smooth component in time (like a sinusoid with 1 year period), but also higher frequencies fluctuations. the smart model would compensate only for the smooth component, while actual temperatures…[Read more]

Thank you so much for the rapid reply!

As for “estimate as well as possible the non linear model”, I wonder what’s the difference between using a non-linear model built by myself(e.g. include deformation induced by temperature or water level) and using the “smart” non-linear model?

Additionally, I know that I can use higher threshold for point…[Read more]

Additionaly, I suggest to use Graph Analysis and Refinement module. It is between APS and SPP button. There is possible to remove low coherence connections and improve APS graph.

Hi,
1. in the APS module the aim is estimating the APS, not the model parameters.
2. the APS is estimated from phase residuals. phase residuals = original phase – model. if the model is wrong, phase residuals will be wrong and the APS will be wrong.
If you have non linear signals, given the 2 above statements, you should either estimate as well as…[Read more]
