摘　　要：对"春雷"号有界波电磁脉冲模拟装置的传输线进行了设计改造,新传输线长27m,宽10m,高6m,采用锥板接分布式负载结构。对模拟装置新传输线的传输性能进行了实测与仿真计算。结果表明:新传输线负载电阻链形成的反射波叠加在波形后延,引起宽脉宽HEMP波形的畸变。同时,新传输线工作空间的电场分布不均匀,与仿真结果相差较大,最大偏差可达18%。A new transmission line of ＂Spring-Thunder＂ bounded-wave EMP simulator is designed and constructed. The transmission line is 27 m long, 10 m wide, and 6 m high, and adopts a subulate plank and distributed terminator structure. The transmission characteris- tics of the transmission line are measured and simulated. The results show that the reflected wave formed by terminal load chains of transmission line is added on the falling edge of wave- form which causes waveform distortion of HEMP. Meanwhile, the E-field shape is not uniformity inside the working volume of the transmission line, and the maximum deviation of E- field strength is 18%.
