[CO-WoP'2025] CNES-ONERA Workshop on Earth-space radiowave Propagation

TSI - Signal and image processing
The objective of this workshop is to present research activities concerning Earth-space radiowave propagation. It will address the following applications: NTN (Non Terrestrial Networks including mega-constellations), mobile communications for 5G and 6G, GNSS (Global Navigation Satellite Systems), remote sensing and radio-occultation. The targeted frequency bands range from HF to EHF, that is from 3 MHz to 300 GHz. Issues related to standardization, e.g. for ITU-R (International Telecommunications Union – Radiocommunications sector) and new frequency ...

Workshop SAR & CRYOSPHERE

TSI - Signal and image processing
Journée colabellisée par le GdR IASIS et le COMET Traitement du Signal et des Images du CNES avec le soutien de Polytech Annecy-Chambéry, Université Savoie Mont Blanc. Description La télédétection est un outil primordial pour l’étude de l’évolution de la cryosphère : neige saisonnière, glaciers, pergélisol, glace de mer, de lac et de rivière… Le radar à synthèse d’ouverture (SAR) est une source d’informations régulières qui fournit des images de jour comme ...
