摘要: 在网络作战体系中, 电磁泄漏探测是敌对双方都十分重视的领域。电磁泄漏探测分为主动探测和被动探测两种, 其中主动探测由发射源对外发射信号, 通过检测具体位置处的信号特征, 得到被测设备、系统或网络的泄漏信息或其它特征信息。针对一种主动传导电磁泄漏发射源进行分析, 结合其工作机理和具体的试验现象, 提出了对应的等效模型。该等效模型按工作频率的高低, 分为高频等效天线模型和低频等效电路模型两类, 通过理论分析了该模型的准确性, 通过电路仿真验证了等效模型的正确性。通过该模型研究, 可以为后续电磁泄漏探测的数据分析提供有力的分析手段。Abstract: Electromagnetic leakage detection is very important in the area of network attack and defense system.Electromagnetic leakage detection can be divided into initiative detection and passive detection.The initiative detection mainly adopts the way to launch signal to special equipment and then detect current/voltage in specific location.When we get this useful information, we can get the knowledge of leakage information or other feature information of specific equipment.This article tries to build an equivalent model based on a kind of initiative conduct electromagnetic leakage source.According to the working frequencies, it builds two models: the equivalent antenna model and the equivalent circuit model.To verify the accuracy of these two models, the article provides theoretical analysis and simulation verification accordingly.The research of these equivalent models are beneficial for further study of electromagnetic leakage detection.
