Description 220-230
We investigate the problem of tracking a moving
source in shallow ocean in a Bayesian framework, using acoustic field
measurements which are more informative than the commonly employed
bearings-only or time-delay measurements. The acoustic field measurement model
is described and compared with the bearings-only measurement model. A general
approach to Bayesian filtering based on the Gaussian approximation model is
then presented. Within this framework, we consider the unscented Kalman filter
(UKF), fifth-degree cubature Kalman filter (CKF­­­5), and
quasi-Monte Carlo Kalman filter (QMC-KF) algorithms that employ different
numerical integration procedures. Simulation results indicate that acoustic
field measurements yield a significantly lower root mean square error (RMSE)
than bearings-only measurements, and that the RMSEs for QMC-KF and CKF­­­­­­­­­5
are much lower than those for UKF and extended Kalman filter (EKF).
