Abstract

The invention discloses a circular array-based super-directivity underwater communication receiver and a communication method. The receiver comprises a power source supply module, a hydrophone circular array, a water acoustic signal receiving circuit, a data processing module and a ZigBee wireless transmitting module; the power source supply module provides working voltages for the underwater communication receiver; and the hydrophone circular array, the underwater acoustic signal receiving circuit, the data processing module, and the ZigBee wireless transmitting module are electrically connected with one another sequentially. With the circular array-based super-directivity underwater communication receiver and the communication method of the invention adopted, the positioning of underwater moving targets is realized; on the basis of a super-directivity deconvolution beamforming algorithm, signals simultaneously sent by a plurality of moving targets can be obtained with a certain bit error rate ensured, the rate of information transmission can be improved, and powerful technical support can be provided for the transmission of ocean detection information.

Description

technical field [0001] The invention belongs to the technical field of underwater acoustic communication, and specifically relates to a circular array-based super-directional underwater communication receiver and a communication method. Background technique [0002] With the development of the marine industry and the in-depth exploration of marine resources and the marine environment, the role of marine information technology has become more and more prominent. Among them, the technical means of marine surveys are also constantly developing. Resources, marine archeology and other aspects are inseparable from underwater positioning and underwater communication technology. Receivers with underwater positioning and underwater communication functions have a wide range of uses, which is of great significance to safeguarding national territorial sovereignty and national rights and interests. [0003] At this stage, compared with the mature radio technology, the field of underwater...
