periz replied to the topic Non-linear weighting meaning in APS processing panel in the forum Sarproz Forum 3 years, 4 months ago
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] -

Hi everyone,
I need some clarification on the non-linear weighting m, M and P in APS processing panel (see the attached image). Specifically, how they are implemented in the APS estimation and what is their mathematical meaning?
Can you indicate me some accademic reference?
thank u!

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. -

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! -

Hi,
I am planning to purchase/order a number of images for using MTInSAR for a bridge monitoring application. I am wondering which image parameters and modes are the best for monitoring the displacements over a longer period of time.
I would like to know the ideal polarization to use for vertical and horizontal movements in the bridge. Which is…[Read more]

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! -
periz replied to the topic APS processing in the forum Sarproz Forum 3 years, 6 months ago
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

Dear SARPROZ
I’m using SARPPROZ’s PSI to process the Sentinel-1 data. I have a question about APS Processing. After Preliminary analysis and Preliminary geocoding, I go to Multi-Image InSAR processing, I have three questions here:
1. I use Linear Trend=30, Height=100, Thermal expans=0.4 and after connections processing, the connection coherence…[Read more] -
