【摘要】 计算机数据的电磁辐射泄漏近来一直受到人们的关注。该文提出了一套利用其辐射信号获取显示信息并重建之的系统。该系统通过天线接收电磁辐射,经放大,A/D转换后,输入计算机,然后对该数据进行处理,重建图像。试验表明,该系统完全可行,并达到满意的效果。更多还原

【Abstract】 Electromagnetic leakage of video display unit becomes the focus of wide interest recently. An image-reconstruction system is presented here using electromagnetic leakage from video display unit. In this system a loop antenna is employed to receive the radiation. After being magnified, A/D transferred, the received data are processed by computer to reconstruct the image. The experiment shows the feasibility and good performance of this system.更多还原
