Purpose

 

This panel is used to subtract or add the displacement calculated with forward modeling to the wrapped or unwrapped interferograms in slant range geometry.

 

Technical Note

 

This panel can be used after the creation of a modeled displacement map in slant range (with Forward Modeling using as reference a slant range image) to subtract it to an interferogram and facilitate the phase unwrapping. After the unwrapping, the same panel can be used to add back the modeled map, then the interferometric processing follows the standard steps (flattening, geocoding, etc.).

If the goal is simplifying the phase unwrapping, we suggest to supply an unwrapped version of the modeled displacement (adding back modeled fringes to the unwrapped map would be a nonsense).

 

Input Files

 

First image

The interferogram (unfiltered, filtered or unwrapped) to which the modeled displacement will be added or subtracted.

 

Second image

The image containing the modeled map (_sint if unwrapped, _fint if wrapped).

 

Add / Subtract

Add or subtract the second image to the first image

 

Output Files

 

Output image

The result of the addition/subtraction of the modeled displacement to the wrapped/unwrapped interferogram.
