Description

technical field [0001] The invention relates to the field of submarine cable detection, in particular to a double probe type submarine cable detection system and a detection method thereof. Background technique [0002] In the field of submarine cable positioning, routing detection and depth detection are one of the most concerned issues for researchers. Routing detection is to detect the laying position of the submarine cable on the seabed and the laying track of the submarine cable on the seabed. Depth detection is to detect the laying depth of the submarine cable on the seabed. [0003] When choosing a submarine cable detection method, it is necessary to consider many factors, including the difficulty of implementation, economic cost, detection capability, and anti-interference capability. Therefore, the submarine cable detection method adopted is the focus of attention on the detection accuracy and distance of the submarine cable. Current submarine cable detection met...
