Ensuring Electromagnetic Compatibility of Radio Electronic Equipment in Conditions of Formation of Unintentional Contact Radio Interference

The article presents the results of the research aimed at studying processes associated with formation of contact radio interference. Contact radio interference belongs to the class of interference caused by the electromagnetic field of a radio transmitter in the near zone on conductive mechanical contacts with a time-varying electrical resistance, or on alternating contacts between structural elements which are secondary emitters of the induced electromagnetic field. The article presents practical recommendations on ways to counteract contact interference and methods of ensuring conditions for electromagnetic compatibility (EMC) of a radio electronic equipment installed on moving objects in the presence of contact interference. The spectra of contact electromagnetic interference created by contacts under the influence of mechanical factors are analyzed. The study of conditions contributing to contact electromagnetic interference on moving objects makes it possible to ensure electromagnetic compatibility and efficiency of radio electronic equipment.
