Radio-detection of UHECR by the CODALEMA experiment

Les Comptes-Rendus 2008, seront publiés EN ANGLAIS et en version électronique sur le site internet de la SF2A. Ils seront référencés dans ADS.International audienceThe CODALEMA experiment is based on an original approach of the detection of radio transients associated with extensive air showers induced by ultra high-energy cosmic rays. Since September 2006, CODALEMA has been under operation with a new setup at the Nançay Radio Observatory, France. We will present evidence for the radio detection of cosmic rays above 10^17 eV, based on an event-by-event analysis and we will discuss the radio characteristics of these showers
