Holographic reconstruction of an incident field assuming the spherical waves scattered by a rigid sphere
Original language description
This paper deals with the reconstruction of an acoustic field in the near-field around a rigid sphere using Near-field Acoustical Holography (NAH) based on an expansion in terms of the spherical harmonics. By employing the rigid sphere providing stable inversion of the propagation function one has to take into account the scattering effect that could significantly affect the total field around the sphere. This effect is commonly accounted for the separation of the incident and scattered field from the total measured field. In applications performing sound field reconstruction by NAH, the presence of source in the near-field of the sphere is to be expected. In this study, such a source in the near-field is considered and a method for determination of the source distance is examined. We consider the spherical waves scattered by a rigid spherical surface for the separation and subsequent reconstruction of the only incident field in this paper. The results are presented in a model simulati
