泄漏电缆周界入侵检测定位技术研究

Study on Leaky Coxial Cable Perimeter Intrusion Detection

针对当前泄漏电缆入侵检测存在的缺乏定位能力和定位精度不高的问题,本文提出了基于格雷码自相关技术的入侵目标定位原理,并在此基础上进行了系统建模与仿真。验证了该原理应用于本系统的可行性,最后搭建了原型测试系统进行了实验,实验结果表明该入侵检测算法能够有效地检测到入侵并具有较好的定位精度。

Aiming at the lack of localization ability and localization accuracy of intrusion detection in leaky cable intrusion detection field,this paper proposes the principle of localization of intrusion targets based on Gray code autocorrelation technique,then the system modeling and simulation are carried out to verify the principle.Results from a field test prove that the detection algorithm could detect the motion of an intruder and has good position accuracy.
