Toulouse France

Director of Research at the CNRS, André Lannes is now at the head of a French working group on the algorithmic aspects of Aperture Synthesis in Radio Imaging and Optical Interferometry. He is also in charge of the image reconstruction group of the Laboratoire d'Astrophysique de Toulouse, and works as a project leader at the Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique (CERFACS). In the framework of a CERFACS/MMSF/ESA contract, he was at the origin of the Y geometry of the MIRAS antenna.

Eric Anterrieu joined the Image Reconstruction Group at the Laboratoire d'Astrophysique de Toulouse in November 1993 as an engineer of research in computer sciences. His present research interests now include image and signal processing, as well as numerical analysis. He is now working for 6 years on european contracts with Matra Marconi Space France (MMSF) and the European Space Agency (ESA) on Earth remote sensing by aperture synthesis (through a CERFACS/MMSF/ESA contract, he was at the origin of the geometry optimization for the bi-frequency extension of MIRAS).

Role in the SMOS mission:

Dr. André Lannes will coordinate the work on the calibration on SMOS. With Eric Antérrieu they will improve and test the image reconstruction algorithm. They will also work on the MIRAS A/C demonstrator and will contribute to the design of the final reconstruction algorithm together with the calibration procedure.
