Real-time, general-purpose, high-speed signal processing systems for underwater research: proceedings of a working-level conference held at SACLANTCEN on 18-21 September 1979 - part 1 : sessions 1 to 3
(NATO. SACLANTCEN, 1979/12)During the last few years, advances in the computer field have reached a level where it is possible to implement fast signal-processing systems through the use of standard computer equipment operating in association with ... -
Reverberation suppression
(NATO. SACLANTCEN, 1995/05)We propose a processing methodology for shallow-water reverberation -
Review of target strength information for waterside security applications
(NURC, 2008)Estimates of the target strength of objects, such as for example scuba tanks and swimmer delivery vehicles, are parameters of interest in all phases of the design of waterside security systems. Results of numerical target ... -
SACLANTCEN real-time signal processing system
(NATO. SACLANTCEN, 1979/12)To meet its increasing requirements in real-time signal processing, SACLANTCEN has developed a general purpose. signal processing system called WARP to be uS.ed with a fairly wide range of underwater acoustic research ... -
Source localization in shallow water using multi-frequency processing of shot data
(NATO. SACLANTCEN, 1996/07)Multi-frequency processing methods are applied to real data generated by explosives to examine the -
Terrain mapping with forward looking sonar on unmanned underwater vehicles
(NATO. SACLANTCEN, 1997)In the future, successful reconnaissance operations conducted in shallow water with Autonomous Underwater Vehicles will rely heavily on a high performance, high resolution, forward look sonar coupled with terrain mapping ... -
The intrinsic variability of detection range and its implications
(NURC, 2009/12)The range of first detection of an approaching target is among the most important parameters defining sensors and defensive surveillance systems. A demonstration of capability typically consists of staged approaches of a ... -
The MPS-3 and the SPS-81
(NATO. SACLANTCEN, 1979/12)The Larqe Aperture Acoustics Branch of the Naval Research Laboratory has developed a sea-qoinq signal processinq system in which two different types of array processors are used - a Signal Processing Systems SPS-81 and ... -
Underwater optical and acoustic imaging: a time for fusion? a brief overview of the state-of-the-art
(CMRE, 2019/06)Underwater optical imaging has several drawbacks inherent to the physical medium such as light attenuation and turbidity. Sonars try to obviate those issues although, typically, they have lower resolutions. Combining visual ... -
Using intelligent graphics terminals in real-time processing
(NATO. SACLANTCEN, 1979/12)At the Naval Research Laboratory intelligent graphics terminals are being utilized for real-time acquisition, storage, processing and display of oceanographic data when mini-computer systems are inappropriate. The intelligent ...
