The purpose of the CODALEMA experiment, installed at the Nançay Radio Observatory (France), is to study the radio-detection of ultra-high-energy cosmic rays in the energy range of 1016 – 1018 eV. Distributed over an area of 0.25 km2, the original device uses in coincidence an array of particle detectors and an array of short antennas, with a centralized acquisition. A new analysis of the energy-reconstruction from radio data is presented for this system, taking into account the geomagnetic effect. Since 2011, a new array of radio-detectors, consisting of 60 stand-alone and self-triggered stations, has been in deployment over an area of 1.5 km2 around the original detection device. This new development leads to specific challenges in terms of recognition of cosmic rays or wave-front analysis.
