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]

finally the linear model with thermal expansion is added.

By the way, the temporal coherence with index “_1” is the coherence before removing APS.

Looking forward to your reply. Thanks very much.

Best regards

the result of linear model is added here

there is some conflict between your operating system/hardware/software configuration and the Matlab MCR. Write to support at sarproz dot come and ask for the Sarproz version compiled with matlab 2017. it might solve your issue
