    Hi dear staffs,
    I have a stack of TSX SLC dataset and want to use it for tomography application.
    After coregistration y SARPROZ, when I apply inversion processing I do not get good results.
    A guess is need for phase calibration or in my opinion baseline calibration (because of unequal baselines).
    Anyone has any idea about this problem?

    What is inversion processing??

    It is the simple Fourier beamforming as :
    g = Ax => x = A’g
    and it is expected to have sinc-like response at position of single (or double) scatterer(s), but there are numerous sincs in output of beamforming.

    This question does not apply to Sarproz and its use. Solving your problem requires analyzing in detail what you are doing, and this cannot be done in a few lines in a forum.
    I can answer that the baseline given by the software is an approximation of a function which is pixel-dependent. Baselines are calibrated, and you can check it by generating interferograms.
