The application of parametric side scan sonar to the detection of proud and buried targets
(NATO. SACLANTCEN, 1998/01)This paper describes an experiment designed to evaluate the feasibility of using the TOPAS parametric transmitter mounted in side scan mode, for the detection of buried targets. The concept was tested with proud targets ... -
The application of spread-spectrum communications to REA tactical networks and deployable underwater surveillance systems
(NATO. SACLANTCEN, 1999/08)The present document is a part of an ongoing study on advanced communication techniques in support of Rapid Environmental Assessment (REA) and Deployable Undersea Surveillance Systems (DUSS). It aims at the definition of ... -
The ARL shipborne computer system
(NATO. SACLANTCEN, 1972/05) -
The Barny program: fourteen years of NURC-NRL collaboration
(NURC, 2009/05)Shallow ocean environments, with their rapid variability, short spatial scales and often intense fishing, pose a special challenge for physical oceanographic study. Since 1995, a series of collaborative programs between ... -
The characterization of a range-dependent environment using towed horizontal array data from the MAPEX 2000 experiment
(NATO. SACLANTCEN, 2002/11)The characterization of ocean environments using geoacoustic inversion techniques has received a -
The continuous gradient ray tracing system (CONGRATS)
(NATO. SACLANTCEN, 1971/12)CONGRATS, an acronym for the Continuous Gradient Ray Tracing System, is an integrated collection of ray tracing programs designed to model acoustic propagation and reverberation. The fundamental programs of the series, ... -
The determination of permeability in in-situ marine-floor sediments
(NATO. SACLANTCEN, 1985/11)A method of evaluating in situ permeability of unconsolidated marine floor sediments has been -
The dynamics of information fusion: synthetic versus misassociation
(NURC, 2006/08)Fusion entails both the association and synthesis of information. If missassociations occur, they obviously undermine the gains won by synthesis, compromising the fusion product. An analytic framework is presented here to ... -
The effect of a layer of varying density on high-frequency acoustic reflection, forward propagation loss and backscattering strength
(NATO. SACLANTCEN, 1997/06)This report examines the impact that a thin layer of varying density would have on high-frequency reflection, forward loss and backscattering of acoustic plane waves from the seafloor. A functional form for density ... -
The effect of gravity-forced oscillations at the base of the duct on its effective depth as a channel for acoustic rays
(NATO. SACLANTCEN, 1971/12) -
The effect of suspended particulate matter on the performance of high frequency sonars in turbid coastal waters
(NATO. SACLANTCEN, 1997)Shallow coastal environments are characterised by high levels of suspended mineral particles relative lo the open ocean and such suspensions can have a significant effect on the performance of high frequency sonars operating ... -
The effect of thermohaline variability on the exchange through Mediterranean straits
(NATO. SACLANTCEN, 1989/05)exchanges through straits. The primary assumption is that the exchange is determined by tlle pressure force created by the differing weights of tlle water columns on either side of the sill and by the continuity of mass ... -
The effect of water column stability on acoustic backscatter from the ocean bubble layer
(NATO. SACLANTCEN, 1997) -
The effect source movements on shallow water bottom backscatter
(NATO. SACLANTCEN, 1997)The time-evolution model BORIS is used to study the effects of source movements on bottom backscatter. Changes in the backscattend time domain signals as functions of source depth, position and incident angles are simulated ... -
The effectiveness of a system-of-systems for countering asymmetric maritime threats in ports and harbours
(NURC, 2008/09)A small boat loaded with explosives has been used by terrorists to attack military and civilian maritime surface vessels at berth or at anchor. For example, suicide bombers attacked the USS Cole using a small boat while ... -
The effects of atmospheric and thermohaline variability on the validation of the GEOSAT altimeter oceanographic signal between Scotland and Iceland
(NATO. SACLANTCEN, 1987/10)Atmospheric and oceanographic profiles from the area between Scotland and Iceland are analysed in -
The fauna of the Strait of Sicily
(NATO. SACLANTCEN, 1972/09)All students of the Mediterranean, both biologists and physical oceanologists, now agree t ·hat the Western and the Eastern basins have rather different features and that the Strait of Sicily is there fore an interesting ... -
The general geophysics and geology of the Strait of Sicily
(NATO. SACLANTCEN, 1972/09)Available geophysical and geological data combined with newly compiled bathymetric, bottom sample, underwater photograph and recently published geophysical data [Ref. lJ have been analysed to describe the geophysical and ... -
The GIN Sea: Review of physical oceanography and literature from 1972
(NATO. SACLANTCEN, 1988/07)A synthesis and review of the physical oceanography of the GIN Sea (Greenland, Iceland, and Norwegian Seas) is presented. An accompanying bibliography complete from 1972 is included. Emphasis is placed on describing the ... -
The hydrological characteristics of the waters exchanged between the eastern and the western basins of the Mediterranean
(NATO. SACLANTCEN, 1972/09)An analysis is done of hydrographic data obtained in 1965 and 1966 in the region of Tunis-Sicily-Malta. Vertical sections permit to follow the opposite spreadings of the surface water of Atlantic origin and the levantine ...
