Supélec ONERA DSTA Research Alliance (SONDRA)

Présentation du laboratoire

Créé en 2004, SONDRA est une équipe d'accueil rattachée à CentraleSupelec, l'ONERA, l'Université Nationale de Singapour (NUS) et le DSO, agence singapourienne de recherche sur les systèmes de défense. Cette alliance quadripartite unique a pour mission de mener des recherches dans les domaines de l'électromagnétisme et du radar. Ses activités de recherche couvrent quatre thèmes scientifiques : la propagation et la diffusion dans des mileux complexes, l'antenne à réseau de phase, le traitement du signal radar et les concepts de nouveaux radars. En particulier, l'équipe SONDRA contribue à l'analyse des nouvelles technologies de détections radar et électromagnétique pour répondre aux besoins de performance des systèmes de surveillance (maritime, aérienne, terrestre et intérieure).
