摘要
为提高海底光缆的探测效率,克服有源磁探测法的缺点,首先从海底光缆自身的铠装出发,提出了磁异探测这种无源磁探测的方法,接着对该方法的原理进行了深入分析,并利用无限长圆柱体模型和磁偶极子磁场模型对其进行了理论推导,其结果对今后开展仿真和实验具有较强的指导意义。
To improve the detection efficiency of optical submarine cables and overcome the shortcomings of active magnetic de-tection, this paper first presents a passive magnetic detection, i.e. magnetic anomaly detection, on the basis of their armoring, then it conducts an in-depth analysis of its principle and carries out theoretical derivation by using the models of infinite long cylinder and magnetic dipole field, which are instructive to the simulation and experiments in the future.
