Multi-resolution localization method based on time reversal and simulated annealing algorithm

Résumé

—In this paper, we propose a novel acoustic indoor localization system that is based on time reversal. The system estimates the target position with different precision. First, it uses a low frequency signal in order to localize the source in the whole area within coarse precision. Then, it switches to high frequency signal to estimate the target location in a reduced area within a fine precision. The system performance have been evaluated by simulations and by experiments conducted in a practical training room in the National School of Engineers of Le Mans. Results have shown that the system has subcentimeter accuracy.
