An electromagnetic wave transmission system and method across the seawater-air interface

Abstract

The invention relates to an electromagnetic wave transmission system crossing seawater-air interface and a method thereof; the system comprises one or more underwater sound-electromagnetic wave subsurface buoys and a monitor platform; the underwater sound-electromagnetic wave subsurface buoys convert underwater sound signals of underwater device received by underwater sound sensors into electromagnetic signals at first; the electromagnetic signals are mainly received by being transmitted to the monitor platform via a lateral wave propagation path of the electromagnetic wave in a medium having a smaller conductivity; in return, the electromagnetic wave control signals transmitted by the monitor platform are transmitted to the underwater sound-electromagnetic wave subsurface buoys via similar links.

Problems solved by technology

[0009] In order to overcome the serious shortcomings of existing underwater wireless communication methods, such as poor real-time performance, large interface influence, poor concealment, and low communication rate, the present invention proposes an electromagnetic wave transmission system and method across the seawater-air interface. The system and method are based on The propagation characteristics of electromagnetic waves in the layered conductive medium composed of seawater and air use the side wave component to effectively avoid the huge attenuation of electromagnetic waves when they propagate directly in seawater, thereby increasing the propagation distance
