Background

At present, the main power driving mode of the underwater equipment adopts a propeller for propulsion, water flow is stirred when the propeller works, a large number of bubbles with long residence time can be generated in a manufactured wake flow, and the acoustic characteristics of seawater containing the bubbles can be changed. In addition, there are a large number of bubbles of different sizes in sea water for various reasons in the ocean, and the acoustic characteristics of the water containing the bubbles are different from those of pure water, and resonance caused by multiple scattering of the bubbles in the water has a shielding effect on sound waves. The method for judging the underwater target by utilizing the acoustic characteristics of the bubbles and the method for eliminating the noise of the underwater equipment by utilizing the bubble groups is a research direction for improving the invisible effect, so that the method for researching the acoustic characteristics of the bubble layer in water has important scientific significance and application prospect.

In addition, ocean garbage is a variety of garbage articles that occur in the ocean and are harmful to the ecological environment, including plastics, glass, metals, chemicals, heavy metals, petroleum products, garbage dumps, and the like. Current ocean waste has a significant negative impact on the ocean.

At present, garbage ships are generally adopted for sea-going collection of ocean garbage, so that manpower and material resources are extremely wasted, the collection cost is high, and the time consumption is long.

In addition, marine noise pollution is a large amount of external noise sources (such as underwater construction and sonar), and has negative effects on marine ecological environment, biological behaviors, reproduction, growth, communication modes and the like. Artificial activities such as port construction, oil platform construction, water channel excavation and transportation, submarine mineral exploitation and the like result in increased ocean noise. The ocean noise has great negative influence on the ocean ecological environment, the current method for reducing or eliminating the ocean noise generally carries out noise reduction improvement on equipment generating the noise, the noise reduction effect is generally, and the research and development cost is high.
