| Research Abstract |
In this research, a novel method for multiple moving sound source tracking is presented. The method consists of two successive algorithms for tacking the signal subspace and for estimating direction of sources. The preliminary experiments showed a serious problem that only one source direction is tracked in a scenario of multiple sources. Then, a roughly peak search method of the MUSIC spectrum is proposed to avoid such a problem. Several experimental results in the actual environment showed that the method could avoid the problem and track the sources in high accuracy.
