The horizontal positioning and interference analysis of submarine buried cable

Submarine cables are routed on the seabed, electricity and data are transmitted through long distance communication undersea submarine cable. In the process of the power and data transmission on the submarine cables, the current generates magnetic field and electric field, so it presents a certain electromagnetic in the seawater. By detecting submarine cables, the electromagnetic characteristics of the submarine cables can be extracted the from the marine environment, the location of the submarine cables can be infered. This paper carry out the research on electromagnetic positioning method and position interference, the location and the disruption of the submarine cable were simulated by numerical method, the specific conclusions are given.
