    Hello everybody,
    I am trying to process a pair of ALOS-2 images using the DINSAR method. But the fringes are located too often and the displacement is too large. I tried to use the function “Residual Fringes Removal”, but this did not change the result.
    Any ideas why this is happening and how to get a plausible result.
    Thank you.

    this interferogram has problems. Either orbital or doppler problems. it needs further investigation
