3D target shape from SAS images based on a deformable mesh
(NURC, 2009/12)The seafloor can nowadays be scanned with side-looking sonar that provides a very high resolution over a large swath, which has proved beneficial for underwater target detection and classification. For systems operated at ... -
A Bayesian approach to predicting an unknown number of targets based on sensor performance
(NURC, 2006/08)Estimating remaining targets after some attempt has been made to detect an overall, unknown number of targets is critical to determining the potential threat associated with these remaining targets. This paper presents a ... -
A classification technique combining aspect dependence and elastic properties of target scattering
(NATO. SACLANTCEN, 1999/04)Discrimination between man-made and natural underwater objects and between man-made objects of different characteristics are the key objectives of target classication. The current approach is mainly based on the analysis ... -
A collection of analytical results related to the ASW protection of convoys and carriers
(NATO. SACLANTCEN, 1987/07)This paper is a collection of diverse analytical results that are related to several aspects of a common problem: the defence of carriers against torpedo-firing submarines. This work is not in any sense a complete treatment ... -
A compact buoy system for ship-use in the measurement of ocean micro-structures over a monthly period
(NATO. SACLANTCEN, 1966/10)The oceanographic buoy described is for ship use. It allows a single ship to make synoptic studies of a limited body of water using a number of buoys. The purpose was to create an economic, simple, dependable sea unit, ... -
A compact thermometer for the study of microthermal structure from oceanographic buoys
(NATO. SACLANTCEN, 1965/10)A solid-state, thermistor thermometer, of small physical size (13 cm x 14 cm), low cost ($21.00 worth of parts), and long-term stability (of the order of 0.01 C in 60 days) is described. It has been used successfully - in ... -
A comparative analysis of side-looking sonars for rapid classification of underwater intruders
(NURC, 2008/09)One aspect of NURC's 2008 efforts in port protection involves building a prototype system for countering a subsurface threat. Such a capability against underwater intruders in ports requires surveillance of the underwater ... -
A contribution to the hydrology of the Strait of Sicily
(NATO. SACLANTCEN, 1972/09)The Osservatorio Geofisico Sperimentale of Trieste made a series of hydrological measurements in the Mediterranean in 1968. The areas concerned were the Gulf of Taranto, the Tyrrhenean Sea and the Western Basin. At. the ... -
A contribution to the study of surface and subsurface zooplankton in the Strait of Sicily
(NATO. SACLANTCEN, 1972/09)Analysis of 71 hauls of plankton in the Strait of Sicily, from 2 February to 16 March 1966, enabled us to make a systematic, quantitative and ecological study of all zooplankton systems present. A synthesis was made, from ... -
A contribution to the study of the surface and deep zooplankton in the Strait of Sicily
(NATO. SACLANTCEN, 1972/09)Analysis of 34 hauls of plankton in the Strait of Sicily, from 5 to 21 May 1970, enabled us to make a systematic, quantitative and ecological study of all zooplankton systems present. Vertical fishing was performed with a ... -
A conversational processing system of acoustic data for use on land and at sea: SPADA
(NATO. SACLANTCEN, 1972/05) -
A data-driven control strategy in synergy with continuous active sonar for littoral underwater surveillance
(CMRE, 2017/11)In this work, we describe a data-driven Mission Management Layer (MML) running on-board AUVs which manages the phases of a littoral surveillance mission and exploits the characteristics of Continuous Active Sonar (CAS) ... -
A deep stepped thermohaline structure deep in the Mediterranean
(NATO. SACLANTCEN, 1972/09)A deep stepped thermohaline structure has been observed in the Tyrrhenian Sea below the Levant ine water salinity maximum. The layers are remarkably homogeneous starting with a thickness of 10 m - 20 m at 600 m and thereafter ... -
A detailed study of sound reflections from a layered ocean bottom
(NATO. SACLANTCEN, 1965/05)The effect of layered sediments on sound reflection from the ocean bottom has been investigated theoretically and experimentally. Very detailed, systematic and computer-aided calculations of the reflection coefficient of ...
