激光窃听行为的检测和预警系统应用
Application of Detection and Early Warning System of Laser Eavesdropping
摘要
Abstract
The technological countermeasures in physical space information security have been developing rapidly.Among them,acoustic information faces significant risks under the threat of laser eavesdropping technology.However,domestic research on detection and early-warning technologies for laser eavesdrop-ping remains limited,leaving only passive protection measures against such threats.The lack of effective countermeasures has hindered the formation of robust adversarial capabilities.To address this issue,an active detection and early-warning method for laser eavesdropping based on multi-algorithm fusion is pro-posed,enabling high-precision detection and localization of laser eavesdropping spots.Experimental results show that a detection and recognition rate of over 90%are achieved in this system for laser eaves-dropping spots,with an average early-warning time of less than 27 s.Convenient deployment,dynamic tracking,audible-visual alarming,and forensic storage functions are also fulfilled.Significantly,an active defense technical solution is provided for laser eavesdropping threats,enhancing the real-time monitoring and emergency response capabilities of information security in critical scenarios.关键词
