摘　　要：在分析低空核爆远区电场信号幅度及频域特征的基础上,设计了信号接收天线和调理电路,并制作了满足室外全天候工作条件的监测系统样机。经标定,系统-3 dB带宽为500 Hz70 kHz,灵敏度为3.4 Vm-1/V。Based on the characters of low - ahitude nuclear electromagnetic pulse, we designed the detection system which includes antenna and signal conditioning circuit. The calibration results show that the - 3 dB bandwidth of detection system is 500 Hz ～ 70 kHz. In additon, the correction factor is 3.4 Vm^-1/V. The application results are presented in the end.
