Four-element planar arrays focus a point-like source based on the artificial iterative phase conjugated processing

Autor: Ting Li, Yi Zhang, Liufang Fu

Publikováno v: INTER-NOISE and NOISE-CON Congress and Conference Proceedings. 265:4718-4724

The artificial iterative phase conjugated processing is an improved algorithm of phase conjugation and has been proven to focus a sharp focal spot using linear array. Because cross-shaped four-element planar array and triangular four-element planar a

Vector Ocean Ambient Noise Spectrum Simulation Based on Parabolic Equation Model in Shallow Water

Autor: Peng Li, Shuqing Ma, Liufang Fu, Chengzhi Gao, Xinhua Zhang

Publikováno v: Journal of Computational Acoustics. 25:1750034

Ocean ambient noise spectrum is one of the most important characteristics of ambient noise. An ocean vector ambient noise field model was built up based on parabolic equation in this paper. Then the spectra of sound pressure, horizontal particle velo

Passive localization techniques of a vector hydrophone based on time-reversal method

Autor: Liufang Fu, Shuqing Ma, Zhou Meng, Yu Chen

Publikováno v: 2013 IEEE/OES Acoustics in Underwater Geosciences Symposium.

The pressure and horizontal velocity signals of a vector hydrophone are adopted together in the time-reversal (TR) processing, which can be used in the passive localization of the underwater target. In order to model the replica field, an improved co
