The article of record as published may be found at https://doi.org/10.1121/1.4983446 For horizontal-looking sonar systems operating at mid-frequencies (1–10 kHz), scattering by fish with resonant gas-filled swimbladders can dominate seafloor and su

Surface scattering strength (SSS) is one of key acoustic inputs to reverberation and active sonar models. This report presents significantly-updated results from 55 broadband SUS SSS measurements in 6 Critical Sea Test (CST) experiments. Since the ti

The limiting influence of clutter on active sonar performance has long been recognized, with echoes from complex bathymetry, fish schools, and anthropogenic objects such as wrecks, capable of producing false target detections that can both mask real

This study examines tank measurements of acoustic backscatter from different scale-model representations of ocean bottom features. The emphasis is on comparing backscatter from a periodic, rippled surface made from machinable blue wax vs. identical s

Geomorphological formations on the ocean seafloor are spatially complex objects. Rock outcrops in particular can be spatially compact, and highly anisotropic in their large- and small-scale topographic structure, and represent a significant source of

This paper presents some new results from measurements of seafloor reverberation and pulse spreading using horizontal and vertical line arrays. The principal objective of this paper is to extract useful geoacoustic and bottom-scattering parameters th

Ocean acoustic propagation and reverberation in continental shelf regions is often controlled by the seabed and sea surface boundaries. A series of three multi-national and multi-disciplinary experiments was conducted between 2000-2002 to identify an

High-resolution acoustic measurements of low-frequency near-surface backscattering at low grazing angles have been made in the open ocean using vertical arrays of coherent sources. Over the range of wind speeds (4-18 m/s) encountered, the normalized

In this article acoustic scattering by a random rough interface that separates a fluid incident medium from an underlying uniform scattering medium, either fluid or elastic solid, in cases for which the Bragg scale lies within the power-law tail of t
