Abstract
A hardware platform using broadband antenna, oscilloscope, and spectrum analyzer is designed to receive radio frequency (RF) signals from electromagnetic radiation leakage of computers in the office environment. The process of receiving and the processing techniques have also been given. Then, the software radio-based computing models and software algorithms are proposed to demodulate and decode the RF signals. An experimental result shows that the text information can be recovered from electromagnetic (EM) leakage wave of computer by this interception system. This architecture not only reduces the cost of the system’s hardware but also makes interception more flexible. The innovation points of this paper are recovering the video information in EM leakage wave of computers in an ordinary office environment based on public equipments and proposing the process of receiving processing techniques that only use the software radio-based computing models and software algorithms.
