Measurement of the height of the Eiffel Tower with interferometry
SAR sensors are echo-localization systems. They measure the time between the emission of an electromagnetic pulse and its reception after that it have been backscattered by targets. This time is firstly converted in distance and then in pixels. The coordinates of…

The Eiffel Tower in SAR imagery
The Eiffel Tower is an emblematic monument in Paris. I have studied it through a temporal stack of 100 images acquired by TerraSAR-X in spotlight mode (thanks to the DLR projet LAN2708). See how it looks in SAR imagery. The image…

DInSAR on the Eiffel Tower for the Gretsi 2015 in Lyon
SAR Interferometry (InSAR) and SAR Differential Interferometry (DInSAR) are two well-known techniques of Synthetic Aperture Radar (SAR) image processing. SAR Interferometry measures the phase difference between 2 images acquired from slightly different points of view to obtain the height of…

In a week of Multitemp 2015, in Annecy
My presentation will focus on the comparison between spatially estimated polarimetric entropy and temporally estimated polarimetric entropy. Indeed, long term temporal series become accessible for SAR images in full-polarimetric mode, thanks to the new lauches of satellites and to the…

Paper accepted as an oral presentation at POLinSAR 2015
The paper deals with the enhancement of the resolution of polarimetric SAR imagery. Due to technical constraints on the system design, the azimuth resolution is coarser in polarimetric images than in the mono-channel acquisition of the same SAR sensor. We…
