Quaternary cross array acoustic detecting system for underwater glider

Abstract

The invention discloses a quaternary cross array acoustic detecting system for an underwater glider, and relates to the field of marine environmental detecting equipment. According the quaternary cross array acoustic detecting system, the problem that in an existing marine environmental detecting system, vertical dimension information of ambient ocean noise with different ocean depths cannot be obtained in a large scale is solved. Four sound pressure hydrophones are all used for obtaining ocean surface vertical dimension sound pressure signals and sending the signals to a datum collecting andstorage module; the four sound pressure hydrophones are respectively fixed to the four wingtips of the empennage of the underwater glider; and the datum collecting and storage module is used for collecting and storing vertical dimension sound pressure signals in the process of underwater vertical section movement of the underwater glider. The quaternary cross array acoustic detecting system for the underwater glider is used for obtaining vertical dimensional marine environmental acoustic information.

Description

technical field [0001] The invention relates to the field of marine environment detection equipment, in particular to a 4-element cross array acoustic system for an underwater glider. Background technique [0002] The hydrophone-based marine environment detection system has the advantages of stable performance, convenient signal acquisition, and low cost. It has great room for development in marine environmental noise observation and underwater target detection and recognition. However, the existing hydrophone-based marine environment detection systems, such as acoustic submersible buoy system and shore-based acoustic observation system, etc., or the scale of the equipment is large, or the working depth and position of the system are fixed, and it is impossible to obtain the marine environment of different ocean depths on a large scale. The vertical dimension information of noise, and with the development of technology, the stealth performance of underwater equipment is gett...
