Cross-steam interface waveguide generation method based on artificial bubbles

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...
