Adaptive normalization of active sonar data
(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, ...
Active detection enhancement in coastal areas
(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 ...
Multi-waveform active sonar tracking
(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
(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 ...
Adaptive sub-band processing in active detection and tracking
(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 ...
