By the way, I also want to ask under these situation, how do we choose Non-Linear Weighting parameters. I usually use the default parameters(0.71 0.84 0.97).

Thanks for the update. I used to have lots of problem with older version while I switched to Matlab 2019 or newer versions. But the new version, so far was awsome.

Hi,
we did not publish anything on this topic. However, the concept is simple: is e.g. 0.7 coherence high or low? it depends! It depends on how many images are in your dataset, on the baseline distributions, it depends on the processing options you have chosen. So, firstly Sarproz runs some simulations to find reference numbers (m the minimum…[Read more]

Thanks for your answer .
After Downloading and installing latest version it worked

Hello, I have a problem, software don’t download the precise orbit files and because I’m in Iran, (https://qc.sentinel1.eo.esa.int/ ) is filtered so I can not manually download the files.
can anyone help me, please.

No, it is not ok

We suggest you to take an InSAR course.
Please check the emails you received to know more about courses.

Dear periz,
Thank you so much for your suggestion, I think my result is pretty good!
On this basis, I would like to ask you another question, I’m processing data from two different sensor in one area, so I’m thinking how can I make sure I’m choosing the same reference point in both processing?
Many thanks!

Okay, I will try again by using 0.7 as the amplitude stability index. Using thermal expansion is because I’m processing Sentinel-1 data from 2014 to 2021, I think over this long time series, the results may be affected by thermal expansion. Of course, I will try your suggestion and don’t use it at this time!
Many thanks!

the result is not bad, actually, it’s pretty ok
do not look at the value of the coherence in the temporal plot, that plot is useful only to look at the trend in time, to check whether there are some left signals that were not well modeled
more suggestions:
* u can take a lower threshold for the amplitude stability index, like e.g. 0.7. in this way…[Read more]

It is not to mutch information to tell exactly. if You have sentinel 1 images stack, You may use first Smart 5 option (remove thermal manualy). Then You got data to analyse how big is tehe movements in AOI
