Reradiation interference computation model of high voltage transmission line to the shortwave radio direction finding station

Till now there is no mature calculation method to analyze the passive interference of the high voltage transmission line to the radio station nearby. Based on the production mechanism of the reradiation, the paper gives the simplified model of the tower and the transmission line by using equivalent way, which make the simulation for the passive interference to realize .Finally, it verified the model's enough precision by comparing it with the shortwave radio direction finding error experiments data, applicable in designing the protecting distance between the UHV transmission line and the wireless radio station nearby in the future.
