In civil aviation, communications between pilots and air trafic controllers are of primary importance. A jamming has been experienced on ground stations working in the VHF frequencyband (118-134 MHz). This has impaired air-ground communications. This phenomenon is due to Corona discharges occurring on the antenna pylon when there is a strong ambient electrostatic field. The aim of this PhD is to develop a model to predict the noise on the antenna induced by corona discharges, for a given geometry and ambient field. Firstly, we localize the places where corona discharges most likely occur via an electrostatic simulations. Then, we propose and validate an elementary dipole model to represent the radiation of corona discharges in the frequency domain. Finally we evaluate the interference introduced by corona discharges at the antenna ports by means of simulations in the frequency domain. The simulation results are compared with measurements.
