I would like to work with Multi Aperture Interfeometry using Sentinel 1 images.
Is there any module which supports this method using SNAP or any other open source software. ?
If a module with Sentinel 1 is not available yet, what are the data sets (like ERS, Envisat ASAR, PALSAR…etc.) can be used for this approach using SNAP ?
Do you have any source for this image?
I think the part which is actually interesting is the merge of interferograms. You make two interferograms, one with a forward looking and one with a backward looking image pair. I am not sure how this is exactly defined, but it is decisive what is done with them in order to make one final product.
Sentinel-1 is probably not suitable for that, I guess you need bistatic airborne systems.
You can. These guys did it
Also, the image comes from here : https://www.researchgate.net/publication/220053910_An_Improvement_of_the_Performance_of_Multiple-Aperture_SAR_Interferometry_MAI
The idea is to do subaperture processing of L0 product to generate a backward and a forward SLC image. It degrades a bit the resolution since you reduce the Doppler Bandwidth
Maybe @lveci can tell us if this process may be implemented in the future ?
that is interesting, thank you for posting the links.
But in this case you need a L0 SAR processor such as ROI_PAC in order to prepare the data because SNAP only takes Level1 products.
True. I would have loved SNAP to do this
Here is the source document.
could some one let me know how to get ROI_PAC software to work on this issue…!
Thanks for the information.
could you let me know the processing steps to be followed to achieve the MAI with sentinel-1 using ROI_PAC.
further, pls let me know that, Is there any other software other than ROI_PAC which can process L0 format data of Sentinel-1?
I’m not experienced in this field, sorry.
Maybe another user can comment here, I am interested as well.
