Study on Acoustic Scattering Characteristics of Fish

2021 OES China Ocean Acoustics (COA), 2021
Using acoustic method to study the fish monitoring technology in aquaculture vessels has many advantages, such as reducing the pressure of the marine environment and improving the quality of fish. The target strength of fish is the main parameter of monitoring and estimation, and it is usually researched by the model approach.

Simulation of Phase Characteristics of Underwater Target Acoustic Scattering

2019 IEEE International Conference on Signal, Information and Data Processing (ICSIDP), 2019
Acoustic scattering phase of underwater target is one of the key scattering characteristics, which can be used as an extra parameter for target detection and an identifier for target identification. On the basis of analyzing and processing the simulation data of benchmark scaled model, the phase characteristics of acoustic scattering signals associated

Guided Acoustic-Wave Brillouin Scattering Characteristics of Few-Mode Fiber

2014 IEEE Photonics Society Summer Topical Meeting Series, 2014
We experimentally investigate the modal dependence of the guided-acoustic wave Brillouin scattering (GAWBS) characteristics in a few-mode fiber (FMF). We clarify that launching higher-order modes into FMF induces different peak frequencies from those of single-mode fiber (SMF) in the GAWBS spectrum and that the GAWBS spectrum strongly depends on the ...

Simulation Study on Acoustic Scattering Characteristics of a SCUBA Diver

2021 OES China Ocean Acoustics (COA), 2021
Based on Kirchhoff approximation, a prediction method on the echo characteristics of a SCUBA diver was presented. Since a scuba diver needs to swing his large fins to overcome the water resistance caused by their diving equipment. As a result, the swing process of the fins may affect the backscattering characteristic significantly.
