Interferogram generation problem (purple image)

how does the coherence look before ESD?

Interesting, the co-registation has been “successful” to a degree, otherwise there would be only spurious coherence and the phase-image would be only noise. Clearly something went wrong somewhere on the way.

I ran coherence estimation before ESD and the result is the same as before. It is better I run all steps from the beginning, as the results show there may be a problem with the previous steps.

so it must be caused during the BackGeocoding step already.

Please re-run it with SRTM 1Sec (AutoDownload) and Nearest Neighbor resampling.

I ran it with SRTM 1Sec (AutoDownload), I re-run it again.
Thank you very much for your guidance dear ABraun
