How to resolve displacement vector in three dimensions from Differential Synthetic Aperture Radar?

19 September 2015 1 7K Report

DInSAR produces the surface displacement in only the direction of radar line of sight (LOS) then, how to resolve this vector in the three dimensions East-West, North-South, and Up-down (vertical) for merging with other space geodetic techniques as GPS

Thomas Fuhrmann

Hi,

you can find a paper on the combination of InSAR with levelling and GPS measurements here: http://gji.oxfordjournals.org/content/203/1/614.abstract

The slides of a presentation on the combination approach held on ESA's Fringe Workshop 2015 in Frascati, Italy, can be found in this pdf-file: http://seom.esa.int/fringe2015/files/presentation80.pdf

The full matrix including the projection of InSAR LOS displacements (ascending as well as descending) is on slide 11.

Cheers, Thomas
