| Abstract(in English) | This paper proposes a new TDOA estimation based on phase-voting cross correlation and circular standard deviation. Based on phase delay and kernel function, the proposed method generates a probability density function (PDF) of TDOA for each frequency bin. TDOA estimate is etermined by voting the PDFs generated for all frequency bins. Peak positions of the PDF for the target signal are concentrated while peak positions of the PDF for the noise are scattered. Therefore, by overlapping the PDFs for all frequency bins, a peak position for the target can be easily identified. The width of PDF is changed by circular standard deviation calculated for each frequency bin. This enhances a peak of target PDF when time change of target TDOA is small. Evaluation with small ship sound and flying drone sound shows that estimation accuracies of the proposed method are better than those of conventional GCC-PHAT. |
