Abstract
This paper analyzes the characteristics of EMC in theory,the results show that it would rather consider the EMC effect among these electronic equipments in short range than in long range.The theoretical research,mathematical simulation and test verifica⁃tion for the performance change of antenna caused by EMC effect of an electronic equipment test in short range are implemented,the results show that the level between main lobe and the first sidelobe is significantly higher,the maximum loss of antenna gain does not exceed 5 dB.The superimposition of multiple unstable signals on signal spectrum is eliminated by cutting off multiple transmission paths. The method of changing test layout is used to avoid the influence of a high⁃power radar in test area.The EMC effect among these elec⁃tronic equipments in short range is inductively analyzed during such two phases as project design and test.关键词
