Some possible interpretations from data of the CODALEMA experiment
The purpose of the CODALEMA experiment, installed at the Nan\c{c}ay Radio
Observatory (France), is to study the radio-detection of ultra-high energy
cosmic rays in the energy range of . Distributed over an
area of 0.25 km, 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 observable in energy for radio is presented
from 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, is being deployed over an area of 1.5 km around the initial
configuration. This new development leads to specific constraints to be
discussed in term of recognition of cosmic rays and in term of analysis of
wave-front.Comment: 13 pages, 12 figures Proceeding of the ARENA2012 conference,
