泄漏电缆在户外周界入侵监视得到了较多的应用。在分析了当前泄漏电缆周界监视技术的基础上,介绍了定位式泄漏电缆周界监视技术的组成框架,将连续波雷达伪随机编码测距原理应用到泄漏电缆目标定位领域。针对当前泄漏电缆周界监视存在的虚警率高以及缺乏定位能力的问题,提出了基于伪随机编码的入侵目标定位原理,并在此基础上研究了修正的单元平均目标恒虚警检测处理方法。通过仿真验证了方法的有效性,并且实现了较高的定位精度。

Leakage cable system finds many applications on outdoor perimeter intruder detection. Based on analysis of current leakage cable surveillance technology, the framework of positioning leakage cable system is introduced. In order to solve the existing problem in current technologies such as high false rate and lacking of positioning capability,the principle of range measurement in continuous wave radar is applied to the intruder location in leakage cable. The positioning principle based on pseudo random code is presented. Based on the principle, the modified unit average constant false alarm rate is studied. Simulation results show the efficiency of the new methods and the high range resolution.
