Abstract A novel method of multi-sources distinguishing is proposed single acoustic vector sensor by detecting the line spectra. The distinguishing capability is found to be only relative to the output SNR of the line spectra. with the direction finding ability of acoustic vector sensor with in low frequency band, the association between the line spectra and the corresponding sources is established by using direction vicinity principle, the multi-sources distinguishing and auto-tracking is then realized with α filtering. Simulations with sea trial data show that adjacent 3 sources with in 10° can be distinguished with single acoustic vector sensor. This method is simple and effective, thus has the prospect of engineering applications.
