中文摘要：
为了更好地分析电晕放电辐射信号的特征，笔者利用尖端电晕放电模拟测试系统采集了电晕放电辐射信号数据，研究分析了信号在时域和频域的一些特性。分析结果表明，电晕放电辐射信号首脉冲的方向随放电电压的极性不同而相反，在不同极性放电电压下，放电辐射信号的时域特征差别比较明显，但频谱分布基本一致，放电能量主要集中存50-100MHz之间，频率范围主要在150MHz以下。
英文摘要：
The radiation signal was sampled by using the point corona discharge simulation system, and the characteristics of the signal in time-domain and frequency-domain were analyzed to analyse the corona discharge characteristic of radiation signal better. The results indicate that the direction of the first pulse of the radiation signal is opposite under different polarities of the discharge voltage. With different polarities of the discharge voltage, the characteristics of the radiation signal in time-domain are different, but in frequency-domain the distributions of the frequency spectrum are basically identical. The energy of the discharge signal concentrates mainly on 50-100 MHz, and the range of radiation frequency is below 150MHz.
