Abstract

Disclosed is a method of underwater communication using an electric field rather than an electromagnetic field. A receiving device detects the electric field by measuring the electric potential or electric current of the electrical field in water. Preferably, the transmitter (Fig. 1) includes one or more pairs of electrodes (4, 5) and the receiver (Fig, 2) includes one or more pairs of electrodes (8, 9). If there are multiple pairs of electrodes they are preferably mutually orthogonal. Information may be communicated by modulating a carrier 1 with encoded data 3, or using electrical impulses to encode the information.

Description

Underwater Electrical Communications
Technical Field
Underwater electrical communication is a technique of sending and receiving message below water.
Background Art
Electroreception, sometimes called electroception, is the biological ability to perceive electrical impulses. It is particularly common among aquatic creatures since salt water is a much more efficient conductor than air, It is used for electrolocation (detecting objects) and for electrocommunication.
Disclosure
According to the invention, the sending device generates the electric field in the water and the receiving device detects the electric field by measuring the electrical potential or the electric current of the electric field in the water. The sending device consists of the generator of the direct current, the device generates electrical impulses, the encoder and electrodes which are placed in water or the sending device consists of the generator of the alternating current, the device modulates the electrical waveform, the encoder and electrodes which are placed in water. The receiving device consists of the device which measures the electrical potential or the electric current of the electric field in the water, the decoder and detecting electrodes which are placed in water.
Description of Drawings
The subject of the invention in example is shown on the illustration in which fig. 1 presents the schema of the sending device consists of the generator 1 of the direct current or the alternating current, the device 2 generates electrical impulses or modulates the electrical waveform, the encoder 3 and electrodes 4 and 5 (when the electrode 4 is the positive (+) electrode then electrode is the negative (-) electrode and vice versa).
Fig. 2 shows the schema of the receiving device consists of the device which measures the electrical potential or the electric current of the electric field in the water, the decoder Z and detecting electrodes 8 and (when the electrode 8 is the positive (+) electrode then electrode is the negative (-) electrode and vice versa).
Fig. 3 presents the schema of the receiving device consists of one device, which measures the electrical potential or the electric current of the electric field in the water, one decoder 7 and three pairs of detecting electrodes and 9 which are arranged on axes X, V and Z.
Industrial Applicability
The subject of the invention can find its use as a civil or military underwater communication system.
