Hello,

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 scheme. I would like to ask: can I directly use my weights as the magnitude, construct complex values accordingly, and save them into the interferograms? Does SARPROZ use coherence directly as weights, or does it apply a transformation (e.g., using $\gamma^2 / (1 – \gamma^2)$ instead of $\gamma$)?

It would be very helpful if you could point me to any references regarding the network-based weighted estimation. So far, the only relevant reference I know is:

Perissin and Wang, 2012, Repeat-Pass SAR Interferometry With Partially Coherent Targets, IEEE TGRS.

Thanks in advance!

Cheers,
Shuyi Yao

correct

yes you can and it will be directly used as weight

that’s the one!
