In the modules APS Estimation, Sparse Points Processing, and Graph Analysis and Refinement, I understand that selecting “Coherence” in the “Weights” option allows SARPROZ to read the interferometric phase from the INTERFEROGRAMS folder and use the magnitude (i.e., coherence) as the weighting factor.

Now, I have developed my own weighting…[Read more]

I have another question. Does “weight data with the coherence” make sense if for the same point its coherence is the same on all interferograms, but the coherence may be different between different points?

In Multi Image InSAR processing (e.g., APS estimation, Graph refinement and Sparse points processing), where SARproz will read the phase from? I know if I don’t have files in the folder “INTERFEROGRAMS”, SARPROZ will read the phases from “FITTED”, and do Flattening and DEM removal. So what if I have already generated interferograms? If…[Read more]

Is there any paper about the algorithm principle of smart mode in SARPROZ? I used smart mode in a manuscript and I wanted to find a most appropriate citation. In addition, I’m curious how does this nonlinear estimation work. I learned that smart mode is equivalent to a filter, but is there a more detailed description of it (like some equations…[Read more]

I want to subsample the data with the aim to eliminate correlations between the resolution cells introduced
by oversampling. Can someone tell me how to do this (with SARPROZ)?

Best regards,
Yao Shuyi
