Purpose

 

The differential phase is generated from the difference of two input interferograms; it is suggested to previously flatten and filter the input data.

 

This functionality can be exploited also for flattening an interferogram by means of a previously generated synthetic phase.

 

Technical Note

 

The input files must be coregistered.

 

It must be noted that, using this functionality for the interferogram flattening, the spectral shift filter is not adapted to the local slope variations.

 

Input Files

 

Interferogram File

File name of the interferogram (_int, _dint, _fint). This file is mandatory.

 

Reference Interferogram File

File name of the synthetic phase (_sint, _int, _dint, _fint). This file is mandatory.

 

Output Files

 

Output File

File name of the output differential interferogram. This file is mandatory.

 

_dint

Differential interferogram with the associated header files (.sml, .hdr).

 

Details specific to the Units of Measure and Nomenclature of the output products can be found in the Data Format section.
