Processing Interferograms
Detailed Description
The second of three steps in interpreting interferograms is processing the InSAR data. In this example, two InSAR fringes are equal to 56 mm of subsidence. The magnitude of displacement represented in one fringe varies based on processing.

Interferometric Synthetic Aperture Radar (InSAR)
Interferometric Synthetic Aperture Radar (InSAR) is an effective way to measure changes in land surface altitude. InSAR makes high-density measurements over large areas by using radar signals from Earth-orbiting satellites to measure changes in land-surface altitude at high degrees of measurement resolution and spatial detail ( Galloway and others, 2000 ). Synthetic Aperture Radar (SAR) imagery is...
