Embodiment Construction

[0016] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0017] The purpose of the present invention is achieved like this:

[0018] (1) At the transmitting end, place the transmitting transducer in the water under the ice;

[0019] (2) At the receiving end, the geophone is used as the receiving antenna, which is placed on the ice surface and tightly coupled with the ice surface. Multiple geophones form a receiving antenna array.

[0020] During equalized decoding at the receiving end, multi-antenna joint processing can be used to obtain space diversity gain.

[0021] 1. The specific implementation of the cross-media communication method:

[0022] Such as figure 1 As shown in Fig. 1, the traditional underwater acoustic communication under ice places the antenna (hydrophone) underwater, and it is necessary to cut through the ice to place the cable. The communication method across the ice medium in t...

Abstract

The invention provides an ice layer crossing medium communication method, and belongs to the field of communication. According to the ice layer crossing medium communication, sound waves are used as carriers; a communication link comprise an emission end and a receiving end; an emission energy converter of the emission end is arranged in the water under an ice layer; a receiving antenna of the receiving end is put on the ice surface; the receiving antenna is tightly coupled with the ice surface; sound signals emitted out from the emission energy converter are coupled to the ice layer media after the spreading through water media; seismic waves are generated; the receiving end builds an underwater-ice layer-on ice acoustic communication link through the vibration information collected by the receiving antenna. The communication link can be built by without the need of putting the receiving antenna under the water level, namely without the need of ice surface cutting through; in addition, the distributive antenna (seismometer) can realize the space respective collection; the signal-to-noise ratio of the receiving signal is improved, i.e., the communication link quality is improved.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a communication method across an ice layer medium. Background technique [0002] In recent years, the development value of the Arctic region in various fields has gradually increased, and it is becoming a new strategic highland for all countries in the world. Underwater acoustic communication technology is an important means to realize the perception of marine environment and develop marine resources. However, the Arctic region is covered by ice all year round. To build a communication link between underwater and ice, it must cross the ice medium. The establishment of a traditional acoustic communication link requires the antenna (hydrophone) to be placed underwater and connected to the base station on ice through a cable. The mobile base station needs to dig through the ice many times to place the cables, which undoubtedly increases the complexity of the project in the...
