Abstract

Acoustic array sensor along with Root-MUSIC algorithm is used to estimate the direction13; of arrival of the acoustic signal emitted by an acoustic target. Three architectures are used to13; track the target in Cartesian coordinates: (i) digital filter with least square estimation, (ii) linear13; Kalman filter with least square estimation, and (iii) extended Kalman filter. A comparative evaluation13; of the three architectures in terms of performance metrics is presented.
