Laboratory testing and on-site experiments to characterize Corona discharges in VHF-band

Abstract

Corona discharges have been designated as aeronautical VHF communications disturber. In order to better understand the discharges, the coupling phenomena involved and to propose an adequate protection for VHF systems, both laboratory testing and experiments on a 25 m high pylon are carried out here. Main characteristics of Corona pulses have been retrieved and analyzed wrt the experimental parameters. Leader propagation phenomena have also been identified.
