An L-shaped Array with Non-Orthogonal Axes – Its Cramer-Rao Bound for Direction Finding
(IEEE, 2017-08)
If a nominally L-shaped sensor-array's two legs are not exactly perpendicular, its azimuth-polar direction-of-arrival estimation would be degraded. This paper quantifies this degradation via a deterministic Cramér-Rao ...
On the Performance of L- and V-Shaped Arrays of Cardioid Microphones for Direction Finding
(IEEE, 2021-01-15)
The L-shaped and V-shaped arrays of first-order cardioid microphones for direction finding are presented in this paper. A comparative study of the direction of arrival estimation performance of the arrays was carried out ...
