This paper reviews the progress in geoacoustic inversion over the past several decades.
The review is separated into two parts. The first part reviews developments in model-based …

Matched field processing is a model-based framework for localizing targets in complex
propagation environments. In underwater acoustics, it has been extensively studied for …

Matched-field based methods always involve the comparison of the output of a physical
model and the actual data. The method of comparison and the nature of the data varies …

Matched-field processing is applied to source localization and detection of sound sources in
the ocean. The source spectrum is included in the set of unknown parameters and is …

Adaptive matched-field processing (MFP) is not only very sensitive to mismatch, but also
requires the received sound levels to exceed a threshold signal-to-noise ratio. Furthermore …

Range-coherent matched field processing (MFP) coherently combines snapshots to localize
a moving, narrowband source. This approach differs from existing MFP approaches that treat …

The two-dimensional (2D) active target localization is generally hindered by the high
temporal and spatial sidelobe levels in snapshot-deficient scenarios, where the adaptive …

Coherent multi-frequency matched-field processing is investigated using a matched-phase
coherent matched-field processor. Its main difference from previous coherent processors is …

This paper develops a series of maximum-likelihood processors for matched-field source
localization given various states of information regarding the frequency and time variation of …

A passive broadband source localization approach in the deep ocean is proposed based on
the coherent matched-field processing combined with a Riemannian distance. The spatial …
