TerraSar-X Processing


How do you process terrasar-x data in sentinel 1 toolbox to generate a DEM?


This has been answered a lot of times in other topics and there is a tutorial for Sentinel 1 Stripmap data which is basically the same:

In general, this is what you do:

  1. Coregister the pair of images
  2. Generate an interferogram
  3. Topographic phase removal
  4. Filter the interferogram
  5. Phase unwrapping (via SNAPHU)
  6. Phase to height conversion

But note that only if you have coherent data the results are of good quality. You can see this after the coregistration of the image pair and the calculation of coherence. The higher the coherence the better the expected output. If there is too much time between the two images coherence decreases.
