چکیده
The scientific objectives of this research are: (1) to develop high-resolution methods for characterizing the spatial and temporal behavior of the normal mode field in shallow water; (2) to use this characterization as input data to inversion techniques for inferring the acoustic properties of the shallow water waveguide; and (3) to use this characterization to improve our ability to localize and track sources.

Modal Mapping Techniques for Geoacoustic Inversion and Source Localization in Laterally Varying, Shallow-Water Environments
An experimental technique is being developed for mapping the normal mode field and its wavenumber spectrum as a function of position in a complex, shallow-water waveguide environment whose acoustic properties vary in three spatial dimensions. By describing the spatially varying spectral content of the modal field, the method provides a direct measure of the propagation characteristics of the wa...
متن کامل10: Efficient Inversion In Underwater Acoustics With Iterative And Sequential Bayesian Methods
Continuing efforts from previous years, we work with Bayesian approaches applied to acoustic signals for the extraction of acoustic features using a combination of physics and statistical signal processing. We are focusing on identifying arrival times and amplitudes of distinct frequencies (within a single mode or across different modes). Those provide significant information on properties of t...
متن کاملRange aliasing in frequency coherent geoacoustic inversion.
This paper discusses the effects of frequency selection on source localization and geoacoustic inversion methods that use frequency coherent objective functions. Matched-field processors based on frequency-coherent objective functions often have rapidly fluctuating range ambiguity surfaces. Insufficient sampling in frequency domain results in range aliasing terms that affect geoacoustic inversi...
متن کاملOcean Acoustics and Signal Processing for Robust Detection and Estimation
Typically, extraction of modal information from the reception of signals that have traveled long distances in dispersive underwater environments is performed with time-frequency or wavelet analysis [5]. Accurate identification of modes and their amplitudes and arrival times is, however, challenging. The uncertainty in the process has an impact on the accuracy of geoacoustic inversion and source...
متن کاملA Markov Chain Monte Carlo Approach for Geoacoustic Inversion and Source Localization
Gibbs Sampling, a Markov Chain Monte Carlo technique, has been shown to be a powerful tool for geoacoustic inversion and source localization. By providing estimates of posterior joint distributions, it offers a global optimization route for multi-dimensional matched-field processing that reports uncertainty and covariance in addition to point estimates. In this work, Gibbs Sampling is applied t...
