Abstract

Abstract

The communication equipment effect mechanism under in-band electromagnetic interference is studied in this paper. Two electromagnetic interference prediction models are established. One model is based on the assumption that in-band interference is sensitive to the amplitude of field strength, and the other is based on the assumption that in-band interference is sensitive to the average power. The sensitive parameter can be distinguished by sine and AM test, and the Equipment Under Test (EUT) interference is predicted according to different models. The sine and AM continuous wave test, in-band dual-frequency test, in-band triple-frequency test are conducted with two typical VHF radios as test objects. Experiment results show that EUT1 is sensitive to the amplitude of field strength, and the model results are slightly greater than 1, and EUT2 is sensitive to the average power. The model results are all approximate 1. The prediction method of in-band multi-frequency electromagnetic interference is modified and improved by the test results. The proposed prediction method is able to forecast the communication equipment interference effectively under the in-band multi-frequency electromagnetic environment.
