Mosaic SLC S1 images


We want to create an interferogram for our entire area of interest.
If one S1 SLC image does not cover the entire area of interest and we need to mosaic it with the adjacent one and form 2 mosaicked interferograms, how can we do this in Sentinel Toolbox?
Actually, we want to avoid the overlapping part (artificial discuntinuity) of two separately produced adjacent interfergrams…

Many thanks!

This should be possible with the SAR-Mosaic functionality. Note that there will be a real discontinuity because the viewing-angle is different, and the baseline is likely to be different as well. Also, since the dates of the 2nd interferogram will differ as well it’s possible that the underlying signal is different too.

That makes sense. How about mosaicking along track? Is it possible to select and mosaic bursts 1-3 from one scene, and bursts 4-9 from the preceding one, to generate a scene that corresponds to a previous image, and then create an interferogram from the two?

Many thanks!


You should do this with the slice assembly. First create your interferograms independently and as a final step use the slice assembly.

hello team
i’m going through SLC products mosaic discussions, as per my knowledge i have understood that it can be done by the slice assembling for two consecutive images.
for me, study area covering the 3 bursts (IW1, IW2 & IW3) in a single image and consecutive image also , but we can do process for single bursts at a time. After that how can we mosaic all these 3 bursts, please help me in finding solution. I think after mosaic all these 3 bursts, slice assembling, can be done for consecutive images. (sorry for my English and lack of knowledge)

thank you in advance.

Please have a look at the following posts,
