I have tried other image pair for analysis (different time and area). I didn't get the discontinuous lines after deburst step. But the unwrapping result still looks strange.
This is another case, I want to detect the creep motion of landslide in mountain area.
The left one is the DInSAR result after filtering, and the right one is the unwrapping result.
I have tried the following thing, but nothing changed of the unwrapping result:
1. Changed the DEM used for topographic phase removed with SRTM(3sec) and ASTER (1sec)
2. Changed the initial method - MCF and MST
3. Changed the tiles row and column from10 to 30 and the tile cost threshold to 1000
4. Chose different time and area image pair to test
And I also tried to masking by coherence > 0.4. But it seems no help?!
Please help me. Many thanks!
