激光窃听行为的检测和预警系统应用OA

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.
