- Abstract
The acoustic field reconstruction using the statistical optimal near-field acoustic holography can avoid the winding error, but the finite aperture error cannot be avoided. In order to reduce the finite aperture error, the data extrapolation technique is used before the separation of the sound field. Numerical simulation shows that the method can effectively reduce the reconstruction error.
