dc.description.abstractAccurate estimation of arrival times along an ocean acoustic ray path is an important component of ocean acoustic tomography. A straightforward method of arrival time estimation, based on locating the maximum value of an interpolated arrival, was used with limited success for analysis of data from the December 1988 Monterey Bay Tomography Experiment. Close examination of the data revealed multiple closely spaced arrivals of similar amplitude, only partially resolved in many returns. A modification to the original tracking algorithm succeeded in improving the estimates and lead to the development of a tracker based on a least mean squares (LMS) linear predictive filter. A second algorithm, based on a modified recursive least squares (MRLS) solution, allows the estimation of dynamic spectral processes at surface and internal wave frequencies in the tomography arrivals.en_US
