In this paper, the induced current in the finite cable near ground is calculated by FDTD method when exposed to HEMP,HPM and UWB pulse respectively. The numerical results indicate that the induced current varies with the length of cable, incident angle and the conductivity of ground. With the same electric field intensity, the HEMP induced current is the largest one among the three induced currents. There's almost no comparable difference between the induced currents in the 5m and 20m cable when exposed to HPM and UWB pulse. The larger the conductivity of ground is, the more quickly the induced current attenuates. When the cable is grounded at one end the current at the grounded end will increase.
