I’d like continue here, although it might not necessarily be related to PAZ data alone.
I have 24 images and calculated coherence between all possible combinations. Most of them look fine and the temporal baseline obviously affects the coherence patterns (stable over urban areas, rapidly decreasing over natural areas)
However, all pairs related with one particular date have strong errors in the coherence, either expressed by systematic stripes or even no coherence except for a stripe in the center of the image
I don’t know how I can cope with this. I tried to increase the number of CGPs for the coregistration and also removed the topographic phase during coherence estimation, but the results were largely the same.
Does anyone have an Idea how I can deal with this faulty date? Its backcsatter intensity looks alright.
