UWB irradiation effects on communication equipment
-
摘要: 为了研究通信装备受超宽带电磁脉冲干扰的影响规律，对某型通信电台开展了超宽带电磁脉冲辐照效应实验。研究发现：在场强为50 kV/m，脉冲下降沿小于1 ns、脉宽小于2 ns的超宽带辐射场下，受试电台出现显示屏显示异常，造成该效应的电磁能量耦合通道为电台显示面板；增大超宽带辐射场至150 kV/m时，短波电台出现显示屏显示异常、死机、重启、声音中断（调谐后恢复）等效应；超宽带脉冲对通信电台的效应只与辐射场强度有关，不存在累积，造成这些效应的电磁能量耦合通道为电台显示面板和供电电源线。Abstract: This paper studies the ultra-wideband(UWB) irradiation effects on communication equipment. Studies have shown that, the malfunction of communication equipment appears when the communication equipment is put in an irradiation field with E-field intensity larger than 50 kV/m, UWB pulse rising edge under 1 ns and duration under 2 ns. The coupling channel here is the display panel of communication equipment. The effects of display panel malfunction, machine halt and restart, and sound stoppage appear when the communication equipment is put in an irradiation field with E-field intensity larger than 150 kV/m. No cumulative effect shows up for the irradiation effects are only related to the E-field intensity, and the coupling channels are the display panel of communication equipme
