dc.description.abstract | Active sonar deployable underwater surveillance systems (DUSS) are based on a distributed network | |
dc.description.abstract | of small multistatic transmitter 1 receiver nodes. This study analyzes the contact localization | |
dc.description.abstract | capabilities of DUSS with experimental data and simple modelling. Localization error medians of 118 m were measured analyzing 450 pings on 3 receivers in 2 frequencies and 3 target trajectories. This error produces a scattering of the contacts of the three receivers around their "barycentre", which is | |
dc.description.abstract | assumed by the multistatic system as the best estimation of the target position. Such scattering was | |
dc.description.abstract | found to be limited to an overall median value of 110 m. The integration of the distributed sonar nodes into a single, extended surveillance system is therefore possible with contact association windows of that size, corresponding to about 100 bearing - range cells. The resulting improvement of contact | |
dc.description.abstract | localization errors was estimated at around 22%. Efficient data fusion methods can therefore be investigated with good expectations. The experimental results do not depend on frequency, target range and trajectory, receiver monostatic / multistatic deployment geometry. Performance objectives | |
dc.description.abstract | and system specifications are also derived for prototype design. The precision of compasses and asset deployment positioning are the most critical parameters. | |
