Problems solved by technology

However, with the increase of various sensor types, the increase of various information, and the increase of noise interference in the underwater environment, the problem of underwater acoustic target recognition has become more and more complicated.
Therefore, relying on traditional methods can no longer meet the current needs, and artificial intelligence methods (such as neural networks) have obvious advantages in dealing with recognition problems with complex environmental information and fuzzy background knowledge.

Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0045] A method for intelligent recognition of underwater acoustic targets based on big data, including:

[0046] The first step: collecting a large amount of underwater acoustic target sound signal data, the collection of a large amount of underwater acoustic target sound signal data meets the preset time, preset classification number, preset channel number, and requires the target position to change;

[0047] The second step: extracting signal features, mainly divided into:

[0048] (1) Splitting the sound signal data of the underwater acoustic target into a preset period;

[0049] (2) Framing each segment of sound signal data;

[0050] (3) performing Fourier transform on the ...

Abstract

The invention discloses an underwater sound target intelligent identification method based on big data. The underwater sound target intelligent recognition method based on big data comprises the following steps of firstly, collecting a large amount of underwater sound target sound signal data, wherein the collected large amount of underwater sound target sound signal data satisfy the preset time,the preset classification number, the preset channel number and the target position change. The underwater sound target intelligent identification method based on the big data has the advantages thatthe received underwater sound signal data are directly processed, so that the real-time performance is high, and the reaction speed is fast.

Description

technical field [0001] The invention relates to the field of underwater acoustic target recognition, in particular to a method for intelligent recognition of underwater acoustic targets based on big data. Background technique [0002] At present, countries are paying more and more attention to the consumption, industry and military status of the ocean, and are vigorously conducting related research. Our country is still in a relatively backward stage. Therefore, with the acceleration of my country's military automation construction, the research on underwater acoustic target recognition needs to be promoted urgently. [0003] In the original underwater acoustic target recognition, the existence and type of the target are mainly determined according to the observer's experience and subjective judgment, and this method has certain disadvantages. Later, acoustic signal theory and modern spectrum theory were used to identify underwater acoustic targets, and the recognition acc...
