A New Joint Localization Model using Multiple Microphone Arrays for Passive Acoustic Source Localization System

The geometrical construction, the number of the microphone and spacing between microphones can affect the acoustic source localization accuracy based on the microphone array (namely acoustic sensor). Presently, the joint localization model using multiple microphone arrays has been widespread concerned because of its wider localization scope, higher robustness and localization accuracy compared with the single microphone array model. Yet, the increase of the number of the microphone in joint localization model with multiple microphone arrays can lead to increase the complexity of the localization system structure and computation, as well as the localization time. So, for this problem, this paper proposes a new joint localization model using multiple microphone arrays based on the generalized cross-correlation method. The simulated results show that the established joint localization model using multiple microphone arrays can accurately locate acoustic source position under the conditions of decreasing the number of the microphone.
