摘要
武器系统的电磁泄漏已成为泄露军事战略意图，暴露重要军事目标的一个主要途径。金属腔体可作为飞机或导弹架构辐射泄漏的屏蔽体，研究其屏蔽效能可为预估飞弹或飞机在此屏蔽架构下的泄漏参考。在此利用FEKO电磁仿真软件建立了金属空腔的模型，并在其内部设置低频Dipole天线作为辐射泄漏信号，仿真和分析了不同形状的金属空腔在频率10～70MHz情况下对于泄漏信号的屏蔽效能。分析的结果表明：铝制金属腔体对于电磁泄漏信号在10～40MHz时具有好的屏蔽效果。
EM leakage of weapon system has been a primary way,of which military strategetic purpose is divulged and important military establishment is exposed. Study of shielding effectiveness of metal cavum, which can be the shielding encloser for airplane and missile,it is the reference for estimating the EM leakage of airplane or missile in the metal cavum. Therefore, in order to study SE of different metal cavum on EM leakage at frequency range 10-70 MHz,software FENO is used to set up the metal cavum model,inside which a low frequency Dipole is placed as EM leakage. The analytical results show that SE of aluminum cavum on EM leakage at frequency range 10-40 MHz is perfect.
