acoustic holography system
According to the principle of near-field acoustic holography (NAH), the system of data acquisition and analysis needed in holographic experiments have been constructed.
ZHANG Guxiang,HE Zuoyong,ZHANG Bing.Near-field acoustic holography on underwater sound sources.
The cyclostationary near field acoustic holography (CYNAH) technique is proposed for cyclostationary sound fields in previous papers.
In order to eliminate Doppler effects in moving sound source identification by acoustic holography,a wavelet transform based method was presented.
Therefore, there are no problems such as parameters interpolation, singular integration etc. in WSA based acoustic holography, which are inherent to BEM based NAH.
