Summary:
In this paper, a method of multiple sound source tracking using microphone array is studied. MUSIC is known as a high spatial resolution method. However, it requires high computation cost. For reducing the cost, PAST-IPLS based on MUSIC has been proposed. Although an evaluation function of IPLS tends to indicate the high spatial resolution by expanding a microphone width, several local minimums tend to appear.Therefore, we propose an avoidance method of spatial aliasing by using a multiplication of evaluation functions of whole frequency bands.
