复杂电磁环境下的装备电磁兼容性

Study on EMC of Equipment under Complex Electromagnetic Environment

复杂电磁环境中存在诸多的电磁干扰因素,在装备的战场适应性方面提出了电磁兼容性要求。为了提高战场生存能力,装备或系统的电磁兼容性应满足GJB1389A"系统电磁兼容性要求"相关规定。针对某型野战装备的特点进行了装备电磁兼容性设计,结合GJB1389A的要求设计了电磁兼容性的具体检验方法;在半电波暗室通过系统自兼容检查、传导安全裕度测试、电场辐射安全裕度测试以及外部射频电磁环境适应性测试等试验验证了装备的电磁兼容性满足要求。

Complex electromagnetic environment contains a lot of electromagnetic interference factors,which require equipment with good electromagnetic compatibility. In order to improve battlefield survivability,the equipment shall meet the relevant requirements of GJB1389 A ＂Electromagnetic compatibility requirements for systems＂. According to the characteristics of a certain type of equipment,its electromagnetic compatibility was improved by grounding,shielding and other methods. According to the requirements of GJB1389 A,the electromagnetic compatibility testing methods of the equipment were designed. It past the tests of self-compatibility,radiated susceptibility,conducted susceptibility and electromagnetic environmental adaptability in semi-anechoic chamber,which proves it was well designed in electromagnetic compatibility.
