Problems solved by technology

[0005] (1) General marine surveys are limited to the observation of individual physical quantities such as sea depth, sea state, and sound velocity, and the perceptual knowledge obtained is limited to the basic level of ocean physics
[0006] (2) Maritime surveys are time-consuming and expensive, and high-density space-time sampling means high time and financial costs, which is uneconomical and unrealistic

Embodiment 1

[0081] The practical ocean acoustic survey spatiotemporal planning method provided by the embodiment of the present invention includes the following steps:

[0082] (1) "Sea area" - for military or civilian needs, the marine acoustic survey sea area is selected;

[0083] (2) "Selection of stations" - comprehensively considering the application requirements of hydroacoustic engineering and the laws of marine physics, select the marine acoustics survey stations in the sea area;

[0084] (3) "Drawing survey line" - according to the experience of hydroacoustic engineering and hydroacoustic physics, design and draw the marine acoustic survey line around the station;

[0085] (4) "Sub-measurement points" - according to the empirical cognition and economy of the spatial variation scale of acoustic quantities, the distribution and investigation content of marine acoustic survey points on the design survey line;

[0086] (5) "Determined Voyages" - according to the empirical cognition ...

Embodiment 2

[0096] The purpose of the present invention is to provide a practical marine acoustic survey time-space planning method, which can not only obtain survey results satisfying the application of underwater acoustic engineering, but also improve survey efficiency and control survey costs.

[0097] In order to achieve the above purpose, the present invention provides a practical ocean acoustic survey spatio-temporal planning method, which includes the following steps: (1) "demarcation of the sea area" - according to military or civil needs, the marine acoustic survey sea area is selected; (2) "selected sea area" "Station" - comprehensively considering the application requirements of hydroacoustic engineering and the laws of marine physics, select the marine acoustics survey station in the sea area; (3) "mapping line" - based on the experience and cognition of hydroacoustic engineering and hydroacoustic physics, Design and draw the marine acoustic survey line around the station; (4) ...

Embodiment 3

[0106] like figure 2 and Figure 4 As shown, the main steps included in the method of the embodiment of the present invention and the main factors that need to be analyzed and considered in the planning process of each step are as follows:

[0107] Step S1 may be referred to as "sea zone" for short. According to the protection of maritime rights and interests (that is, military needs), or the needs of marine resources development (that is, civilian needs), the marine acoustic survey sea area is selected on the chart. ①The surveyed sea area should of course cover the hot spots of marine rights and interests; ② the surveyed sea area should include waterways entering and exit these rights and interests hotspots; ③ the surveyed sea area should include the surrounding fortress areas set up to protect these rights and interests hotspots.

[0108] Step S2 may be referred to as "selection of a site" for short. Investigate the distribution of seabed topography (isobath), mesoscale ...

Abstract

The invention belongs to the technical field of ocean survey and underwater acoustic engineering, and discloses a practical method, system, equipment and terminal for overall space-time planning of ocean acoustic survey. Selecting a survey station in the survey sea area; taking the station as a center radiation survey line; measuring point distribution and survey content on the measuring line are determined; planning a survey voyage number; selecting a long-term fixed-point standing position; and planning survey content, a data return mode and station service life. The marine acoustic survey space-time planning method provided by the invention can provide a simple and effective method and basis for task planning and scheme formulation of marine acoustic survey, and fills the blank in related aspects. Compared with a traditional space-time sampling method which directly replaces a surface with points or is uniform and high in density, the planning method provided by the invention can guide marine acoustics survey actions to obtain survey object space-time sampling with more reasonable density and establish more reliable and comprehensive marine acoustics characteristic cognition at a lower cost-efficiency ratio, thereby better serving underwater acoustic engineering application.

Description

technical field [0001] The invention belongs to the technical field of marine survey and hydroacoustic engineering, and in particular relates to a general planning method for space-time sampling of marine acoustic survey. Background technique [0002] At present, marine acoustics investigation is a scientific research activity and method for people to understand marine acoustic phenomena and master their laws. Ocean reverberation, marine acoustic environmental elements and other data, materials and information. The purpose of marine acoustics investigation is to serve people's utilization of marine acoustic laws, which is a fundamental work closely related to applications (especially military applications). Although general marine surveys also involve marine acoustic elements, they are limited to observations of individual physical quantities such as sea depth, sea state, and sound speed, and the perceptual knowledge obtained is limited to the basic level of marine physics....
