Les connaissances sur les rayons cosmiques d'ultra haute énergie (E>10^{18} eV) ont progressé durant la dernière décennie, en particulier grâce aux résultats remarquables de l'Observatoire Pierre Auger. La question de la composition du flux de rayons cosmiques à ces énergies reste cependant ouverte. Le projet EASIER (Extensive Air Shower Identification using Electron Radiometer) de détection radio des gerbes atmosphériques recherche de nouvelles observables liées à la nature du rayonnement cosmique primaire, complémentaires de celles déjà mise en oeuvre à l'Observatoire Pierre Auger. Ce dispositif est constitué d'un réseau d'antennes radio fonctionnant aux fréquences MHz et GHz et installées en mode esclave sur une soixantaine de détecteurs...
