Localization of an Acoustic Emission Source Based on Time Difference of Arrival
The paper presents results of localization of an acoustic emission source in the two-dimensional space based on signals acquired using microphones and the TDoA (Time Difference of Arrival) technique. The delay between signals in the channels is measured using their cross-correlation. Then the location is obtained using multilateration. The Firefly Algorithm and Gradient Descent Algorithm are used for the purpose of estimating the location.
