Abstract EN
Near-field acoustical holography (NAH) based on the equivalent source method (ESM) is an efficient method applied for noise source identification.
As l2-norm-based regularization cannot produce a satisfactory solution of the ill-conditioned problem in high frequency, the conventional ESM is restricted to relatively low frequency, and the resolution of conventional ESM in middle to high frequency remains a limitation open to investigation.
This article presents an algorithm known as improved functional equivalent source method (IFESM), designed to enhance the resolution of conventional ESM.
This method is developed in the framework of wideband acoustical holography (WBH) combining with functional beamforming (FB).
Through numerical simulations, it is proved that the proposed method can localize noise with higher resolution compared with WBH and conventional ESM, and the ghosts on noise source map can be suppressed effectively.
The validity and the feasibility of the proposed method are manifested by experiments including single-source and coherent-source localization.
