摘　　要：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。In order to improve the electromagnetic compatibility （EMC） of vehicle-mounted communication system, the rational 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 subsequent EMC strengthening and use of the communication system.
