Abstract

A pre-processing method for the holography measurement data is proposed to solve the problem caused by the multi-path interferences in finite space. In order to verify the effectiveness of this method, a standard steel plate is measured in an anechoic tank. The sound reflection coefficient of the steel plate is reconstructed by near-field acoustic holography (NAH) technology using the pre-processed data. The experimental results showed that: using the pre-processed data to reconstruct the sound reflection coefficient by NAH can effectively suppress the effect of multi-path interferences, and improve the measurement accuracy. And more, the requirements for the measurement environment are not very strict. Therefore, this pre-processing method will have broad application prospects.
