Institute of Electrostatic and Electromagnetic Protection ,Ordnance Engineering College, Shijiazhuang 050003 China) Abstract: The EMP characteristic of corona discharge was analyzed in this paper. The corona radiation field of certain battle plane was calculated by using commercial electromagnetic modeling software FEKO 5.1. The radiation directivity diagram of different frequency inspirator is analysed. Key words: corona; directional diagram; simulation; airplane
