Research on Underwater Communication by current Field through silt layer

摘要

In order to meet the communication requirements of the underwater survey in the Yellow River, based on the electrical conductivity of water, this paper proposed the idea of underwater communication using current field. The model of underwater current field communication channel was also made according to electromagnetic field theory. The relationship among the received signal, transmitting voltage, communication distance and other parameters were analyzed. Underwater current field communication devices were then developed. It was proved by test that the bi-way underwater communication of such devices was correct, reliable, and easy to perform, thus a practical and feasible communication means for the underwater survey in the Yellow River silt layer was provided.
