Abstract

The invention provides a method and a system for reducing loss of radar detection power caused by a power transmission line. The method comprises the steps of determining the center position of a power transmission line and painting the center position with a magnetic material; painting the two sides of the power transmission line with a magnetic material from the center position thereof at fixedintervals. Through cooperation of the technical solution provided by the invention and working frequency, the induced current peak position of a power transmission line is painted with a magnetic material with simple operation and low weight, so that the intensity of induced currents can be suppressed and the loss of detection power of meter wave band radar caused by the power transmission line can be reduced.

Description

technical field [0001] The invention relates to the field of electromagnetic environment testing of transmission lines, and more particularly, relates to a method and system for reducing power loss of transmission lines to radar detection. Background technique [0002] After the transmission line is erected, electromagnetic waves emitted by nearby radio stations or distant radio incident electromagnetic waves will produce electromagnetic scattering on the transmission lines, overhead ground wires and iron towers, which will affect the reception effect of nearby radio receiving stations, that is, passive interference. influences. [0003] In the prior art, to reduce the influence of passive interference on transmission lines, it is generally adopted to install magnetic rings on the lines or on towers. However, for radar stations operating at higher frequencies, the installation of magnetic rings on the lines increases significantly. The weight of the line is increased, and i...
