Problem with Interferogram Creation

Hi, I have been facing the same issue. For me, the source of error is the S1 TOPS REGISTRATION STEP itself. Can you please check that after stacking, the two slave and master files are generated, what are their intensity files. For me, slave goes zero all the time. Check stats thing, you can find the range of values in the file. For me they are between 0 and some small value. A quick response will be highly appreciated. Thanks!

I am also facing the same issue. For me, the slave intensity is between zero and some very small value. This renders any further step redundant and also leads to purple screen on checking phase. Can everyone who’s facing this issue kindly check their slave intensity file. Just to ask, are you all following https://media.asf.alaska.edu/uploads/pdf/current_data_recipe_pdfs/generate_insar_with_s1tbx_v4.1.pdf or similar tutorial posted their ?
