Title
The Effect Of Calibration Errors On Source Localization With Microphone Arrays
Abstract
Source localization employing time-differences-of-arrival has been employed for many applications. The accuracy of source localization is limited by the errors in the time differences of arrival estimation as well as microphone position calibration errors. Because a microphone position error will affect multiple time differences of arrival, correlation between these quantities will be introduced. This work presents a new mathematical framework in which we quantify the localization performance of a microphone array in which the microphone positions are subject to such errors.
