Abstract

This paper presents a method for Acoustic Emission (AE) source localization in isotropic plate-like structures based on the Extended Kalman Filter (EKF). The accuracy of the traditional triangulation methods depends on the time of flight (TOF) measurements and on the group velocity assumption so uncertainties in both should be taken into account and filtered out. An algorithm based on the Extended Kalman Filter (EKF), capable of filtering out these uncertainties, has been developed for the estimation: 1) the AE source location and 2) the wave velocity. Experimental tests have been carried out on an aluminum plate to show accuracy and robustness of the proposed approach.
