M. Zhang et Mh. Er, CALIBRATION OF SENSOR CHANNEL DELAY UNCERTAINTIES FOR LINEAR MICROPHONE ARRAYS IN FAR-FIELD, Journal of circuits, systems, and computers, 6(6), 1996, pp. 607-618
In this paper, we present three new methods to calibrate the microphon
e channel delay uncertainties, and to estimate the talker location for
linear microphone arrays in the far held. The proposed methods are ba
sed on different a priori information and can be applied to different
cases, respectively. The proposed methods are simple and practical. Th
e estimate errors are analytically derived and analyzed. Computer simu
lations and theoretical computations support the proposed methods.
