The model accounts for the towing vessel's temporally correlated motion and the oceanic currents' space-time correlated behavior. The result is a correlation matrix of the sensor array transversal displacement, which can be used for Bayessian auto-calibration DOA estimation techniques, or to evaluate the best achievable DOA estimation accuracy. cav_un_auth*0212908 ICASSP 2002 Orlando US 13.05.2002-17.05.2002 BB SI http://hdl.handle.net/11104/0130902 UTIA-B 20020029 2002 2002 Orlando IEEE 0-7803-7403-7 Proceedings of the IEEE International Conference on Acoustics, Speech and Signal Processing 2841 2844
