TL;DR: The main thrust of this study is to review the underwater surveillance scenario within a framework of four research areas: (i) underwater robotics, (ii) acoustic signal processing, (iii) tracking and distributed information fusion, and (iv) underwater communications networks.
Journal ArticleDOI
Distributed data fusion for real-time crowding estimation
TL;DR: This approach to estimating the number of pedestrians present in a real-life complex scene by processing a sequence of images improves the estimation accuracy obtained by using only current available data, and can predict crowding values between two successive acquisitions.
Journal ArticleDOI
A computationally efficient finite element model with perfectly matched layers applied to scattering from axially symmetric objects.
TL;DR: A frequency-domain finite-element technique for computing the radiation and scattering from axially symmetric fluid-loaded structures subject to a nonsymmetric forcing field is presented and one particularly useful feature of the Berenger perfectly matched layer is that it can be applied across the interface between different fluids.
Journal ArticleDOI
Measurements and modeling of acoustic scattering from partially and completely buried spherical shells.
TL;DR: A positive result demonstrates the applicability of low-frequency methodologies based on resonance analysis to the classification of buried objects, and is based on the comparison of measurements with appropriate scattering models.
Journal ArticleDOI
Beam pattern formulation and analysis for wide-band beamforming systems using sparse arrays
TL;DR: The BP for wide-band signals is redefined on the basis of beam-signal maxima, and a quasi-closed form of the analytical formulation is achieved for any inter-element spacing, supporting the design of very sparse arrays that show beam-pattern profiles of great interest for imaging applications.
