Abstract

The invention relates to a static ocean reverberation measurement and acquisition method and device. The method comprises the following steps: acquiring calibration parameters measured by a survey ship at a central site of a site sea area; adjusting and binding transmitting and receiving parameters of a hydrophone at the central site according to the calibration parameters; arranging at least one buoy or subsurface buoy at the central site according to the transmitting and receiving parameters; and based on the at least one buoy or subsurface buoy, receiving an acoustic signal emitted by the survey ship at each corresponding measuring point along each measuring line radiated outwards from the central station, and carrying out reverberation characteristic statistical analysis. No matter from equipment configuration or from survey line, survey point and route setting, while the reverberation survey target is ensured to be achieved, the acoustic propagation survey requirement is considered to the greatest extent, the marine acoustic survey cost can be well reduced, the survey efficiency can be well improved, and the blank in the related aspect of marine acoustic survey is filled up.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic engineering, in particular to a method and device for measuring and collecting static ocean reverberation. Background technique [0002] Ocean acoustic survey is a scientific research activity and method for people to understand ocean acoustic phenomena and master their laws. data, data and information such as acoustics and ocean acoustic environmental elements. The purpose of ocean acoustic survey is to serve people's use of ocean acoustic laws, which is a basic work closely related to applications (especially military applications). Ocean reverberation is the sum of all scattering effects on the sea surface, sea bottom, and ocean water body, and is one of the main background interferences of active sonar. Good anti-reverberation performance is a must for active sonar (especially low-frequency sonar), for which it is necessary to understand the intensity, power spectral density, pro...
