This paper proposes a new circular microphone array model in which the distance between the array and sound source can be considered.
In environmental phenomenon conventional estimation method with the steering vector represented by plane wave source may result in poor performance.
To correctly estimate source location, a steering vector is considered under multipath propagation environment and statistical properties are shown.
We show the effectiveness of this direction-of-arrival estimation in a simulation. |
