Description

technical field [0001] The invention relates to the field of underwater electric field communication, in particular to a towed multi-electrode array underwater electric field communication device. Background technique [0002] As the latest generation of non-acoustic communication technology, underwater electric field communication technology has huge potential application value in special application scenarios such as underwater robots, frogman command, unmanned underwater vehicles, torpedoes and ships. Due to the severe attenuation of high-frequency electromagnetic waves by media such as seawater, the underwater acoustic communication technology based on ultrasonic waves is the only underwater communication solution that has been practically applied. It is small, has strong directionality, and is bulky, making it difficult to meet the application requirements in the above-mentioned special scenarios. The underwater electric field communication technology realizes communic...

Problems solved by technology

However, its communication range is mainly determined by the distance between electrodes. The larger the distance between electrodes, the greater the communication range. The electrodes of existing underwater electric field communication devices are fixed on the carrier, which is limited by the size of the carrier. The distance between electrodes is short, about tens of centimeters The communication range is only a few meters to tens of meters, which is difficult to meet the needs of practical applications
