1)the deformaion map has some abnormal information, for example the subsidence part (red 0.017) appears to be too large compared to the uplift part (blue 0.757).
2)Why does the middle part look so complicated? Is this caused by snaphu or the terrain itself?
yes, these patterns are probably causing unwrapping errors. You might try different interferogram filter configurations, especially, the Sigma value of the Goldstein filter could be lowered to avoid artefacts in noisy areas.
Thank you. It’s a good solution to my problem. By the way, for my first question, through many experiments, I found that it was caused by many earthquakes in a short time
