Fringe 2020 Abstract Submission has been opened

I’d like to submit something based to the PAZ data I receive from HisdeSAT (24 images, both ascending/descending and large/small incidence angle).
But interferometry over the urban area is hard and I don’t expect any elevation changes. Do you think an analysis based on coherence would be of interest? Any ideas what I could investigate by systematically compare the coherence products of different configurations?
