摘要

摘要: 該文通過通信裝備帶內(nèi)電磁干擾效應(yīng)機(jī)理研究，分別以峰值場(chǎng)強(qiáng)敏感和平均功率敏感為基礎(chǔ)，建立了兩種用頻裝備帶內(nèi)多頻電磁干擾預(yù)測(cè)模型，提出一種電磁干擾預(yù)測(cè)方法。首先通過單頻和調(diào)幅波試驗(yàn)確定受試裝備的敏感參量，然后根據(jù)不同敏感參量模型對(duì)某電磁環(huán)境下受試裝備是否會(huì)受到干擾進(jìn)行預(yù)測(cè)。該文以不同制式通用通信裝備為試驗(yàn)對(duì)象，通過帶內(nèi)雙頻、帶內(nèi)三頻電磁輻射效應(yīng)試驗(yàn)對(duì)預(yù)測(cè)方法進(jìn)行了驗(yàn)證。試驗(yàn)結(jié)果表明：通過單頻和調(diào)幅連續(xù)波電磁輻射敏感度之間的差別能夠區(qū)分受試設(shè)備符合哪種帶內(nèi)多頻電磁干擾預(yù)測(cè)模型，對(duì)干擾峰值場(chǎng)強(qiáng)敏感的EUT1預(yù)測(cè)模型效應(yīng)指數(shù)都略大于1，對(duì)干擾平均功率敏感的EUT2預(yù)測(cè)模型效應(yīng)指數(shù)都在1左右。以此為基礎(chǔ)提出了通信裝備帶內(nèi)多頻電磁干擾預(yù)測(cè)方法，能夠有效解決通信裝備帶內(nèi)多頻電磁干擾預(yù)測(cè)問題。

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.
