Annual Progress Report 1999
(NATO. SACLANTCEN, 2000)
Project 03F - 1: phase 1 completion report
(NATO. SACLANTCEN, 2002/12)
This report describes the results of Phase I of Project 03F-1. The overall aim of this project is to
Infrared detection of marine mammals
(NURC, 2005/12)
An infrared (IR) binocular, designed for in-the-field military applications, was tested using in situ marine mammals during the Mar Ligure Joint Experiment 2003 (MLJX03) that took place in August-September 2003 onboard the ...
Performance assessment of the LYBIN - 2.0 propagation-loss model
(NATO. SACLANTCEN, 2001/07)
A new acoustic model LYBIN has been proposed for inclusion in the AESS model set. In order to determine this model's prediction accuracy and computational efficiency, SACLANTCEN was tasked to test LYBIN on exactly the same ...
Spectral integral representations of monostatic backscattering from three dimensional distributions of sediment volume inhomogeneities
(NATO. SACLANTCEN, 2001/03)
A theory is developed for generating short time, monostatic reverberation realizations caused by three dimensionally distributed volume inhomogeneities in stratified media. A spectral integral approach to treating the ...
Real-and synthetic-array signal processing of buried targets
(NATO. SACLANTCEN, 2002/01)
Results from two field experiments aimed at investigating the detection and classification of buried targets are presented. In both experiments a 2-16 kHz parametric source was used. In the first experiment the source was ...
A study of the uncertainty in estimate seabed properties as a result of goeacoustic inversion algorithms
(NATO. SACLANTCEN, 2003/10)
This paper investigates the inherent uncertainty in estimated seabed properties derived from matched-field geoacoustic inversion algorithms. This algorithm-induced uncertainty must be considered when interpreting inversion ...
Statistical normalization of non-Rayleigh reverberation
(NATO. SACLANTCEN, 2000/02)
Low-frequency active sonar systems operating in shallow water are primarily limited by reverberation.
Noise measurements during MAPEX 2000
(NATO. SACLANTCEN, 2002/03)
During MAPEX2000 some simultaneous ambient noise measurements with an HLA and satellite SAR images were collected. The aim was to predict shipping and wind noise from the satellite radar and to compare results with acoustic ...
An automatic approach to ship detection in spaceborne synthetic aperture radar imagery: an assessment of ship detection capability using RADARSAT
(NATO. SACLANTCEN, 2000/12)
This report describes a methodology for automated ship and wake detection in space-based synthetic aperture radar (SAR) imagery. The methodology incorporates a multistage approach involving several algorithms which can ...
