Missing bursts after TOPS Split

Please visually check if both products contain two bursts after applying TOPS Split.

master image contains 2 bursts but slave image contains only 1 burst


I don’t know what is the solution please help thank you very much

Please repeat the TOPS Split operation to make sure that both bursts are included in the product.




I chose one burst to generate interferogram and the problem is always in the second

The same is reported here: Back geocoding producing empty stripes in slave product
Looks like that the images are shifted along track and one does not have full burst coverage reaching the displayed footprint. Can you please check if the missing burst is visible before TOPS Split?


the missing burst are visible before TOPS Split

what happens if you select two instead of one burst?



master image contains 2 bursts but slave image contains only 1 burst

@jun_lu do you have an idea?

Can you please provide more details such as the two products you used and the two bursts in master and slave? We will see if we can reproduce the problem. Thank you

bursts in master are 4-5 in IW2
bursts in slave are 7-8 in IW2
I want to generate DEM in this area
thank you all in advance

We assume S1A is the master and S1B is the slave. The problem is that bursts 4-5 in master and bursts 7-8 in slave do not cover the the same area. There is one burst shift. Try use burst 8-9 in slave and it should work.

thank you so much

please,I do subset to interferogram befor unwrapping but I don’t get any product after execute phase unwrapping

Was snaphu installed correctly?

snaphu is installed correctly, snaphu_unwrapping today does not work . yesterday was doing but when finished there was error at row9 but the processing finished without ant resulting product

Did you apply it on the same data? Before you run it again, please make sure to delete temporary files in the folder (unw_[…].img and the tiles folder).
I recommend running snaphu from the command line because it is less prone to configuration errors.

thank you so much. Iam running snaphu from the command line.
please, I have RMSE of the derived elevations for area of study, which were calculated in comparison
with the 557GCPS.(rmse=25 for ALOS 12.5 and rmse=4 for SRTM 30)
(RMSE=17 for DemInSAR(b_perp=119M and b_temp=37 day))
(RMSE=85 for DemInSAR(b_perp=82M and b_temp=12 day))
(RMSE=20 for DemInSAR(b_perp=176M and b_temp=6 day))
but I know rmse=5 for ALOS 12.5m
What do you think of these results?
this is area of study
