Abstract

The invention relates to a towed linear array device based on attitude real-time measurement vector hydrophones. The towed linear array device comprises a switching section, a first vibration damping section, an acoustic array section, a second vibration damping section, and a tail rope section which are arranged successively. The switching section is connected with the towing cable of a mother ship. The towed linear array device is characterized in that the acoustic array section comprises attitude real-time measurement vector hydrophones, submarine acoustic signal amplifying and filtering modules, 16-channel acquisition and transmission modules, depth sensors, and a data transmission control module; and the attitude real-time measurement vector hydrophones comprise attitude sensors. The towed linear array device uses the attitude real-time measurement vector hydrophones, prevents a digital section of a conventional towed linear array, and is simple in structure, capable of distinguishing the larboard and the starboard of a target in real time, and really improving target detection precision by means of acoustic signal attitude correction.

Description

technical field [0001] The invention relates to an underwater acoustic signal receiving device, in particular to a towed line array device of a vector hydrophone based on attitude real-time measurement. Background technique [0002] The vector hydrophone is a new type of acoustic receiver that first appeared in the United States in the 1940s and was introduced into my country at the end of the last century. It can measure the sound pressure scalar and vibration velocity (or Acceleration, displacement, sound pressure gradient) vector, compared with the traditional sound pressure hydrophone, it has the advantages of small size, light weight, effective resistance to isotropic interference, large space gain, etc., which can well solve the problem of sound pressure water The problem of blurring the left and right sides of the target when the earphone array is oriented improves the accuracy of target detection. At present, the towed line array composed of sound pressure hydrophones...
