ROI PAC
Encyclopedia
ROI_PAC is a software package created by the Jet Propulsion Laboratory
division of NASA
and CalTech
for processing SAR
images to create InSAR
images, named interferograms. ROI_PAC stands for Repeat Orbit Interferometry PACkage. It is a UNIX
based software package.
Although many sources exist discussing how to install and use the basic features of the program, there was never a complete user manual created on how to use the software.

Synthetic aperture radar
Synthetic-aperture radar is a form of radar whose defining characteristic is its use of relative motion between an antenna and its target region to provide distinctive long-term coherent-signal variations that are exploited to obtain finer spatial resolution than is possible with conventional...

Interferometric synthetic aperture radar
Interferometric synthetic aperture radar, also abbreviated InSAR or IfSAR, is a radar technique used in geodesy and remote sensing. This geodetic method uses two or more synthetic aperture radar images to generate maps of surface deformation or digital elevation, using differences in the phase of...
