Embodiment Construction

[0020] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0021] Considering the serious attenuation of electromagnetic waves in seawater and the short transmission distance, the present invention creatively proposes a method for generating a waveguide across the water-air interface based on artificial bubbles, which is suitable for the uplink across the water-air interface. The method of the present invention is mainly used for the transmission of electromagnetic waves across the water-air interface in shallow seas. Considering that the attenuation of electromagnetic waves in seawater is mainly caused by the medium characteristics of seawater, the method of artificially intervening in the medium to generate bubbles is used to create dense bubbles and change seawater. The relevant characteristics of the medium are used to improve the underwater channel and reduce the attenuation of electromagnetic waves under...

Abstract

The invention discloses a cross-steam interface waveguide generation method based on artificial bubbles. The method is mainly applied to the cross-stream interface uplink transmission of the high-frequency electromagnet wave (megabytes frequency) in the process of reaching a sea surface receiver by penetrating seawater at the shallow sea surface. The method comprises the following steps: a waveguide device integrated with a bubble generation device and an antenna is used underwater, the bubble waveguide generating unit is used for producing a underwater bubble layer, and a signal emitted by a signal emitting unit is propagated to the water surface through the underwater bubble layer. The equivalent dielectric constant and the conductivity of a seawater specific space are changed by use of the bubbles, and then the electromagnetic wave transmission environment is changed, the transmission of the high-frequency electromagnet wave at the megabytes frequency in the bubble waveguide is realized, and the signal has enough energy to accomplish the air-based and space-based signal transmission after crossing the seawater interface. The method disclosed by the invention is simple in operation, high in secrecy, green and environment-friendly, the technical blank in the cross-steam interface transmission is filled; therefore, the high-frequency electromagnet wave can break the attenuation barrier and can be really applied to the underwater communication field.

Description

technical field [0001] The invention relates to the technical field of cross-water-air interface communication, in particular to a method for generating a waveguide across a water-air interface based on artificial bubbles, which is mainly used in the process of high-frequency electromagnetic waves (100M frequency) passing through seawater in shallow seas to reach sea surface receivers uplink transmission across the air-water interface. Background technique [0002] The current communication across the water-air interface is generally one-way timing communication, which has poor timeliness. When it is necessary to send a signal, it needs to float to the periscope or the water surface state to perform short-wave, ultra-short-wave or satellite communication through an external antenna. With the development of detection technology, this method is not conducive to concealment, so it is necessary to find a new underwater signaling method for water-air cross-interface uplink commun...
