| Submarine cable communication is a necessary method in moderncommunication because of unique virtue, while route detection and fault location is a key technology on keeping communication fluent.This paper deduces the distribution of signal magnitude when the detector is in a different place and optimal signal transmission frequency through studying theory of alternating magnetic field detection. It presents a model that is submarine cable detection with jamming through applying the theory of audio frequency jamming about coaxial cable. According to jamming model, it analyses a varying rule of detection signal while detector moves. And it deduces the relation between zero displacement error and distance between two submarine cables. |
