| 摘 要： | 由于环境噪声的影响,重建TEMPESTATTACK设备截获的电磁泄漏信息的质量很差。为此,介绍一种互相关处理技术的基本原理及在检测弱信号中的应用。首先提出了用互相关技术提取行同步信息的新方法,并用Matlab仿真加以验证,最后对TEMPESTATTACK设备输出的视频信号进行了互相关平均处理,使重建的信息图像稳定、可辨识。

| Abstract: | Due to the influence of environmental noise,the leak emanation information intercepted by TEMPEST ATTACK equipment is very weak and reconstruction information is poor.Therefore introduces the theory of cross correlation technique and its applications in weak signal detection.A new(method) is used to pick-up synchronous information via cross correlation technique,which is proved by Matlab emulation software.Finally,the video signal is correlative averaged from the TEMPEST ATTACK equipments,making reconstructed information image stable and readable. |
