Multi-temporal InSAR and multi-dimensional phase unwrapping
Final report (40 MB pdf)
GIAnT - Generic InSAR Analysis Toolbox website
"Multi-temporal InSAR (MT-InSAR) techniques are unique in their capability of simultaneously estimating the temporal and spatial characteristics of surface deformation over a large area of interest with sub-centimeter accuracy. I'm interested in understanding the effects of wavelength, resolution and orbit repeat periods on MT-InSAR accuracy and performance. I'm also interested in the development of multi-dimensional phase unwrapping algorithms that can incorporate other geodetic deformation measurements, like GPS, to constrain MT-InSAR deformation estimates."
Agram has been working on analyzing the recent Japanese Earthquake using InSAR data. Some of the results are being widely circulated, including on the European Space Agency website.
