First of all the goal of the step I want to apply is, Exclude the infgms, those they are not well unwrapped, then I think this is other issue, since it is clear in the manual as I posted before and here below again and highlighted the STEP 7,
In my opinion, instead of dropping interferograms, I would apply the ramp estimation to remove the ramps/trend and not the interferogram itself, as you got many interferograms with ramps, so your final analysis will have only few interferograms left.
Keep it simple. Once you know better how to use the different options, increase the level…
That is my advice, you can always take it or not. Until now they brought you to a good point.
Yes, It works fine as I mentioned in previous post, but would you please to give some tips concerning the ramps estimation and removing. IsIt should be applied after step 7?
And then 're apply step6?
This is done during step 7.
After running step 7, you always should re-run step 6 (whatever option had scla_deramp), or at least is what I have always understood
Could you please plot the ps_plot(‘u-dmo’,1) and share it here?
I like more this latest results, as now are not ramps there anymore. You could see what you have removed using the command ps_plot(‘o’,1) .
Answering to your question, well, you could try to use TRAIN, the toolbox for atmospheric noise removal developed by David Bekaert, and there you can use weather models, and other data to reduce the APS of the scene.
In fact, the trends you have removed using the ‘o’ option, other people say that are tropospheric ramps, and not orbit ramps, so you could also use this toolbox to help you removing noise.
Additionally, you could use GPS data or similar to reduce bias and fit your output to that, but it is something more difficult that one forum thread can handle.
Still, I invite you to look for this techniques in literature and see what you could think to use/apply.
Another option is to use the step 8 integrated in StaMPS, which does a spatio-temporal filtering to estimate APS signal. Then, for removing it the option is ‘s’ (from slaves) and should be used as follows: ps_plot(‘u-dmos’,1) but I cannot recall if this option is not supported. Just check it out
Yes, It is possible, how to define, might be I didn’t read all the manual, or I didn’t see anything related to define rp manually, would you please refer to it,
