摘　　要：根据超宽带(UWB)纳秒电磁脉冲的基本特性,采用模拟计算仿真与实验研究方法,研究了超宽带纳秒电磁脉冲信号通过微波接收机带通滤波器的时域、频域传输特性,初步认识了超宽带纳秒电磁脉冲通过带通滤波器传输特性规律,它是对传统连续波(CW)信号与脉冲调制信号通过微波带通滤波器传输特性技术的补充和完善。该研究成果为将来开发超宽带纳秒电磁脉冲在各类接收机中的应用提供技术基础。The basic transmission characteristics of Ultra Wide Band(UWB)nanosecond electromagnetic pulse signal via microwave receiver Band Pass Filter(BPF)is explored on time domain and frequency domain by using simulation calculation and experimental methods.It is the complement to the transmission characteristics study of traditional Continuous Wave(CW)signal and pulse modulation signal through microwave BPF.A preliminary law of transmission characteristics of UWB nanosecond electromagnetic pulse signal through microwave BPF is obtained,which can provide technical basis for the future applications of UWB nanosecond electromagnetic pulses in all kinds of receivers.
