为了提高车载系统的电磁兼容性,在设计阶段就需对其进行合理的电磁兼容设计,并且电磁兼容工作要贯穿该项目的全生命周期,因此需要采用恰当的方法对其实际的电磁兼容性进行系统的测试验证.提出了一种适用于车载通信系统的系统级电磁兼容性测试验证方法,通过对系统安全裕度、天线隔离度与驻波、通信射频兼容(含互扰、谐波和互调)、舱体屏蔽效能等项目的实际测试,实现对车载通信系统的系统级电磁兼容性的全面测试和验证.测试结果和获取的数据可以有效指导后续的电磁兼容加固和通信系统的使用.
為瞭提高車載繫統的電磁兼容性,在設計階段就需對其進行閤理的電磁兼容設計,併且電磁兼容工作要貫穿該項目的全生命週期,因此需要採用恰噹的方法對其實際的電磁兼容性進行繫統的測試驗證.提齣瞭一種適用于車載通信繫統的繫統級電磁兼容性測試驗證方法,通過對繫統安全裕度、天線隔離度與駐波、通信射頻兼容(含互擾、諧波和互調)、艙體屏蔽效能等項目的實際測試,實現對車載通信繫統的繫統級電磁兼容性的全麵測試和驗證.測試結果和穫取的數據可以有效指導後續的電磁兼容加固和通信繫統的使用.

In order to improve the electromagnetic compatibility(EMC)of vehicle?mounted communication system,the ra?tional EMC design should be done in the whole life?cycle of the project design. The systematical test for actual EMC should also be executed with a proper method. A system?level EMC testing method suitable for vehicle?mounted communication system is in?troduced in this paper. The overall testing and comfirmation of the system?level EMC are realized by actual testing of the system′s safety margin,isolation between antennas,standing wave,communication RF compatibility(interference,harmonic and inter?modulation),cabin shielding effectiveness and so on. The testing results and the acquired data can be used to facilitate the sub?sequent EMC strengthening and use of the communication system.
