Fixed-depth marine acoustic information acquisition system based on wave glider

Abstract

The invention discloses a fixed-depth marine acoustic information acquisition system based on a wave glider, and belongs to the field of marine environment detection equipment. The objective of the invention is to solve the problems of difficult long-time continuous observation, limited observation range and large noise interference of detection information of an existing marine acoustic information acquisition system. The wave glider of the system is located on the water surface, and an underwater towed body is connected to the wave glider through a fixed-depth towing cable and a telescopic damping mechanism; the fixed-depth towing cable is a carrier for the wave glider to communicate with the underwater acoustic towed body; an acoustic beacon is arranged on the wave glider and is used for sending positioning acoustic pulses to the underwater three-dimensional acoustic three-dimensional array at regular time; a hydrophone converts acoustic signals in the ocean into electric signals, and an acoustic data acquisition and transmission module acquires and filters the signals and synchronously stores the signals in an internal memory in combination with accurate longitude and latitudeinformation of the underwater three-dimensional acoustic three-dimensional array. The system is mainly used for acquiring fixed-depth marine acoustic information.

Description

Technical field [0001] The invention belongs to the field of marine environment detection equipment, and specifically relates to a system for acquiring marine acoustic information in a fixed depth. Background technique [0002] Marine acoustic information is an important parameter of the marine environment, including marine environmental background noise, marine biological acoustic signals and ship acoustic signals. Various marine environmental parameters can be obtained through marine acoustic information, and it is also an important parameter that affects sonar performance. . [0003] Current marine acoustic information acquisition systems, such as shipborne acoustic observation systems, underwater target acoustic observation systems, and shore-based array acoustic observation systems, etc. Shipborne acoustic observation systems consume large amounts of human and material resources and are difficult to observe continuously for a long time; The system can only observe at fixed po...
