摘　　要：针对市面上泄漏电缆入侵检测系统探测精度低、误报率高、数据无法存储问题,提出了一种基于恒虚警的定位式泄漏电缆入侵检测技术。本文采用相关算法用于解决单一频率探测精度低的问题,同时采用单元平均恒虚警和删除式恒虚警算法解决固定门限误报率高的问题。最后,本文进行了在实际应用环境中检测系统的性能测试实验。测试结果表明,入侵检测系统的探测精度为2米,误报率低于10%,不需要前期矫正就可以自适应于不同背景环境噪声,具有良好的应用前景。In the market,leakage cable intrusion detection system have more problem,such as detection accuracy is low,false alarm rate is high,the data can not be stored,a new detection technique of location-based leakage cable based on Constant False Alarm（ CFAR） is proposed. In this paper,the problem of low detection accuracy of single frequency is solved by using correlation algorithm,and using the Cell-Averaging（ CA） CFAR to solve the problem of high false alarm rate of fixed threshold. Finally,introducing the performance of the detection system in the practical application environment. Test results show that the detection accuracy of the intrusion detection system is 2 meters,the false positive rate is less than 10%,and it can adapt to different background noise without pre-correction. It has a good application prospect.
