摘　　要：在缆线的高空电磁脉冲(HighaltitudeElectroMagneticPulse,HEMP)耦合试验研究中,为得到电流注入法与辐射法之间不同波形皮电流的耦合等效关系,将电流注入法时域测量与理论分析相结合,以九芯电缆为例通过芯电压与皮电流的关系求取多芯电缆传输函数。Matlab计算结果表明,通过脉冲电流注入法求解电缆传输函数是可行的,其正确性也得到了验证。In study of HEMP coupling testing for cable, nine-core cable is used as an example. To obtain the coupling equivalent relation of the skin current of different waves between current injecting method and radiation method, the time-domaln measurement of current injecting testing is combined with theoretical analysis. The cable transfer function is established by calculating the relation of core voltage and skin current. The calculated results by Matlab indicate that this method is feasible, and its correctness has been verified.
