摘　　要：根据海缆路由及埋深检测系统精度与实时性需求,提出了一种基于有源交流电磁法原理的五探棒边长可调型海缆探测天线阵。从理论角度研究了单根探棒探测模型和五根探棒阵列排布形式,建立了基于五棒阵列的三种海缆路由定位模型。根据数值模拟,分别获取了海缆偏距、埋深与探棒感应电动势对应关系曲线,分析了阵列边长对探测精度的影响。在此基础上构建了分布式海缆探测天线阵检测系统,实现了对海缆路由及埋深的快速高精度检测,路由定位精度达到97%,比传统哑点法高出2.5%,埋深检测精度达到94%。研究结果能够为海缆及各类埋地管道探测领域提供有效帮助。A five-probe submarine cable detection antenna array with adjustable side length is proposed based on the active AC （alternating current） electromagnetic method and according to the accuracy and real-time requirements of submarine cable route and burying depth detection system. The single probe detection model and five-probe array arranging type are studied from theoretical point of view, and three submarine cable route location models based on five- probe antenna array are established. The corresponding relation curves between submarine cable offset, burying depth and the probe induced electromotive force are respectively obtained according to numerical simulation;the impact of side length on detection accuracy is analyzed. On this basis, a distributed submarine cable antenna array detection system was built. The submarine cable route and burying depth can be detected quickly and accurately. The route location accuracy reaches 97% ,which is 2.5% higher than that of the traditional dumb point method;and the detection accuracy of burying depth reaches 94% . The study results can provide effective help for the detection of submarine cables and various types of underground pipes.
