Prediction method of acoustic scattering from elastic target with structure anechoic coating layer at low frequency

2016 IEEE/OES China Ocean Acoustics (COA), 2016
The prediction method of acoustic scattering from elastic target with structure anechoic coating layer is investigated at low frequency. The physical model is acoustic scattering from elastic shell with structure anechoic coating layer. The transmission matrix method and parameter matching method are used to obtain the parameters of the equivalent ...

The absorption characteristics of anechoic coating embedding mixed-cavity structure with single or double shell backing

Proceedings of the 2010 Symposium on Piezoelectricity, Acoustic Waves and Device Applications, 2010
Rubber sheets embedding air cavities are wide used as anechoic coatings to reduce the energy of sound waves reflected by underwater structures, with a great military and use benefit to underwater vehicle sound stealth. According to the backing type, it can be divided into two kinds, namely rubber sheets-steel-air and rubber sheets-steel-water-steel-air,

Target strength analysis using reflection coefficient of a submarine with low-frequency anechoic coatings

Proceedings of the Institution of Mechanical Engineers, Part M: Journal of Engineering for the Maritime Environment
As the technological development of modern weapons systems progresses, attack and defense against the weapons systems of the past can become useless. In the case of underwater weapon systems, improvements in sonar and torpedo technology necessitate enhancements in submarine stealth performance.

Influence of geometric factors on the acoustic absorption performance of three-dimensional dual-graded anechoic coatings

Physica Scripta
Abstract Given the inherently three-dimensional (3D) nature of practical underwater applications, this study investigates the influence of geometric factors on the acoustic absorption performance of three-dimensional dual-graded anechoic coatings (3D DGAC).
