Problems solved by technology
[0005] Due to the particularity of the water environment, underwater communication is subject to many restrictions
Underwater multi-sensor or robot collaboration generally requires short-distance communication, but the current common underwater communication methods cannot provide a good solution. Under the influence of obstacles, optical communication is easily affected by water quality, such as suspended particles and plankton in seawater, which will have a great impact on light transmission

Description
technical field [0001] The invention relates to the technical field of underwater communication, in particular to an analysis method for underwater electric field communication. Background technique [0002] With the continuous improvement of human production and living standards, the resources on land can no longer meet the demand, and human beings gradually shift the focus of development to the ocean. The current ocean development relies on the assistance of underwater robots. Multi-underwater robot collaboration requires underwater communication technology, and underwater electric field communication is a good solution. [0003] In recent years, people have made preliminary achievements in the research of underwater electric field communication. Many scientific research institutes have proposed their own electric field communication systems and successfully achieved the goal of underwater electric field communication. However, the analysis method and analysis software fo...
