High Sediment Concentration Underwater Communication Using Current Field
Abstract:
The Yellow River is the muddiest major river in the world. It has thick bottom sediment and its water has low light transmittance, which can make sound signal, laser, radio waves through it attenuated and communication distance in its waters limited. So it is unable to meet the communication requirements of the underwater survey. In order to solve the problem, based on the electrical conductivity of water, an idea of underwater communication using current field was proposed, a 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.
