San Andreas Fault System Modeled Interferometry

Radar Line-of-Sight Deformation
3-D deformation accumulated over a 10 year period is calculated and then projected into the ERS-1/2 line-of-sight (LOS) projection according to the following equations [Sandwell et al., 2002]:

Ascending = 0.38x + 0.09y - 0.92z
Descending = -0.38x + 0.09y - 0.92z

Interferometry
Both ascending and descending interferograms of the above line of sight projections are displayed here. One fringe represents 28.28 mm of displacement in the line of sight direction.
