A novel algorithm for near-field acoustic source localization
i.e.
range and Direction-of-Arrival (DOA) estimation by using a velocity sensor array is proposed in this paper.Compared with the existing algorithms
the proposed one has the following advantages:No need to compute higher-order cumulants
hence having lower computational loads; achieving automatic pairing in range and DOA estimation
and having no limitation of the intersensor spacing within 1/4-wavelength
and enabling to obtain higher estimation accuracy by increasing the intersensor spacing for a larger array aperture.Monte-Carlo simulations are presented to verify the efficacy of the proposed algorithm.
