Echoes, as measured through the receiver of an active monostatic sensor system, will
typically fluctuate from ping to ping as the beam emitted from the system scans across a …

In this work, model-based methods are employed, along with machine learning techniques,
to classify sediments in oceanic environments based on the geoacoustic properties of a two …

Understanding acoustic scattering from objects placed on the interface between two media
requires incorporation of scattering off the interface. Here, this class of problems is studied in …

In March 2010, a series of measurements were conducted to collect synthetic aperture sonar
(SAS) data from objects placed on a water-sediment interface. The processed data were …

Understanding the physics governing the interaction of sound with targets in an underwater
environment is essential to improving existing target detection and classification algorithms …

Underwater target elastic acoustic scattering and other acoustic scattering components are
aliasing together in the time and frequency domains, and the existing signal processing …

The scattering from roughly meter-sized targets, such as pipes, cylinders and unexploded
ordnance shells in the 1–30 kHz frequency band is studied by numerical simulations and …

Results from a workshop organized in 2006 to assess the state of the art in target scatter
modeling are presented. The problem set includes free-field scenarios as well as scattering …

For floating bodies in shallow sea, the prediction of acoustic radiation requires consideration
of complex acoustic environments. Generally, the influence of the sea surface, seabed and …

Based on the three-dimensional sono-elasticity theory for ship structures, the Green's
function is incorporated and an integrated calculation method of acoustic radiation and …
