On the 30th of September 2008, Sandra Valcarès defended his thesis on the following subject: Cosmic ray properties from the electric fields measured by the CODALEMA experiment. Sandra work was in particular focusing on the development of a linear predicting method to enhance the cosmic ray radio signal identification. The summary of his document is the following :

This thesis is dedicated to the study of high energy cosmic rays that penetrating the atmosphere and dissipating their energy by producing a very large amount of secondary particles called an air shower. The CODALEMA experiment is measuring the radio counterpart associated to these air showers by using antennas in the 1-100 MHz frequency domain. From the characteristics of the air shower some questions have been studied in order to determine the main effects giving rise to the radio signal. In a second part, we have develop a linear prediction method to identify transients associated to air shower in the noise environment of the experiment. Finally, possible signatures of the radio emission mechanism have been searched for in the experimental signals. This last study is linking the two previous analysis.
