Abstract The current distribution on the shield cable irradiated by electromagnetic waves was greatly associated with the ground. How to obtain the induced current on the cable theoretically is an important foundation of simulating the aircraft in the state of electronic countermeasures. Interferences are usually caused by cable coupling energy, no matter what is common mode or different mode interference. By means of transmission line model with a distributed source, this paper provides a correction expression of the transmission line parameters. The corrected parameters can be available to 1GHz within the margins of error ±5dB. Meanwhile, trial comparisons are carried out, which offer a basic foundation for the aircraft confrontation test in the lab.

Key words： Induced current on the cable transmission line model with a distributed source cable- ground coupling longitudinal impedance
