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.
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 ?
