1.4.5.5. Interferograms Processing


Help for Interferogram Processing

With this function the tool processes interferograms according to the loaded images graph.
The options for interferogram processing can be chosen from the "InSAR Parameters" module.

Interferograms are saved as complex images, in which the phase is the interferometric phase and
the amplitude is the estimated coherence.

SIGN OF INTERFEROGRAMS

There are 2 conventions for the interferograms sign, InSAR and PSI-InSAR.

InSAR: MASTER-SLAVE, and interferograms are written on disk with name SLAVE_MASTER.

However, PSI-InSAR uses the convention SLAVE-MASTER.

Thus, each line in the Images Incidence Matrix contains first a "1" and then a "-1",
corresponding to SLAVE (1) and MASTER (-1)
or likewise each line of the Graph Matrix contains indexes to SLAVE and MASTER images
(SLAVE,MASTER)
However, the corresponding interferogram saved in the directory "INTERFEROGRAMS", will
be named "SLAVE_MASTER" BUT it will contain the interferogram with opposite sign: MASTER-SLAVE
