Active detection enhancement in coastal areas
Haralabus, Georgios; Baldacci, Alberto; Laterveer, Rene (NURC, 2006/08)The processing chain used for active detection analysis in association with measures of performance that allow real time performance monitoring is presented. Real life examples demonstrating environmental volatility ... -
Adaptive normalization of active sonar data
Baldacci, Alberto; Haralabus, Georgios (NURC, 2006/08)In active sonar detection the background interference is reduced through normalization prior to applying a detection threshold. From the two mainstream normalization algorithms, i.e. the sliding window and the split window, ... -
Adaptive sub-band processing in active detection and tracking
Baldacci, Alberto; Haralabus, Georgios; Coraluppi, Stefano; Prior, Mark K. (NURC, 2007/11)Broadband active systems have the potential to increase detection performance in reverberation-limited areas through increased signal bandwidth, i.e. small resolution cell. However, large bandwidth could over-resolve the ... -
Bottom reflection properties deduced from an ambient noise: simulation of a processing technique
Harrison, Chris H.; Baldacci, Alberto (NATO. SACLANTCEN, 2002/11)A promising new method has already been proposed [SACLANTCEN SM-387] to calculate bottom reflection loss from ambient noise directionality. Although this method has been tried experimentally at more than 11 sites under ... -
Cardioid receive array calibration for active systems
Baldacci, Alberto; Haralabus, Georgios; Van Velzen, Marcel (NURC, 2006/08)Nowadays active detection improvement relies significantly on advanced sensor technology, such as the cardioid receive array that allows the directional (right/left) discrimination of the received signal. However, in ... -
Impact of seafloor and water column parameter variations on signal-to-background ratio estimates: a sensitivity study based on sonar performance modeling
Baldacci, Alberto; Haralabus, Georgios (NURC, 2006/08)Regardless of how accurate modeling can be, if the set of assumptions made with regard to the propagation conditions are not precise, sonar performance predictions diverge from the corresponding measured values. Here a ... -
Infrared detection of marine mammals
Baldacci, Alberto; Carron, Michael J.; Portunato, Nicola (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 ... -
Multi-waveform active sonar tracking
Coraluppi, Stefano; Carthel, Craig; Hughes, David; Baldacci, Alberto; Micheli, Michele (NURC, 2007/06)This paper extends the NURC distributed multihypothesis -
Signal processing for an active sonar system suitable for advanced sensor technology applications and environmental adaptation schemes
Baldacci, Alberto; Haralabus, Georgios (NURC, 2006/08)An overview of the basic elements of an active sonar system in conjunction with a description of the signal processing chain utilized at the NATO Undersea Research Centre for detection and localization of undersea targets ... -
The Ninth International Conference on Information Fusion (Fusion 2006) final conference report
Coraluppi, Stefano; Baldacci, Alberto; Carthel, Craig; Willett, Peter K.; Lynch, Robert; Marano, Stefano; Farina, Alfonso (NURC, 2006/10)The 9th International Conference on Information Fusion (FUSION 2006) was held on 10-13 July 2006 in Florence, Italy. The FUSION conference series serves as the annual gathering and
