        Hello,

        I doubt the Def. trend results of my “Small Area Processing”.
        All the images I’ve created have high negative values in the northern part and high positive values in the southern part.
        This pattern appears in all my images.
        An example is attached to this message.
        Is there somebody who knows what causes this pattern?

        Thank you in advance,
        Jan Peppelman

          You cannot use the small area processing for such a wide area.
          Small area processing is suitable for areas where you can neglect the atmospheric delay (less than 1km for C band).
          If the area is bigger, results are not reliable.
          You could easily see that by checking the temporal coherence.
          You need to take a course on the subject
          best
