Scope of this paper is to investigate the performances of different identity declaration fusion algorithms in terms of probability of correct classification, supposing that the information for combination of the inferences from the different classifier is affected by measurement errors. In particular, these information have been assumed to be provided in the form of confusion matrices. Six identity...
3-D target position estimation can be obtained by a system of 2-D netted radars performing a suitable fusion of the 2-D plots or tracks from the different located radars. In this paper we discuss the performance of different systems of 2-D netted radars in terms of accuracy of the height estimation. In particular the difference between a monostatic and bistatic system will be investigated.
The International Maritime Organization (IMO) adopted the following definition of e-Navigation: “e-Navigation is the harmonised collection, integration, exchange, presentation and analysis of maritime information onboard and ashore by electronic means to enhance berth to berth navigation and relat-ed services, for safety and security at sea and protection of the marine environment”. A pre-requisite...
High resolution in range and Doppler are recommended to border surveillance X-band radars for the detection of small RCS ground targets in a severe clutter environment. This kind of radars can also be employed for sea border control. However, in this case the radar processor should suppress the sea spike echoes that can be otherwise mistaken with small boats. In this paper a solution for mitigating...
This paper compares two different approaches for sensor selection for distributed tracking: 1) the Frisbee method, and 2) global node selection (GNS). The Frisbee method is based on the proximity of the nodes to the predicted location of the target; GNS is based on minimizing the unbiased Cramer Rao lower bound (CRLB). Both theoretical and experimental results indicate that the Frisbee method is as...
In this paper we investigate the k-connectivity threshold of distributed dense ad hoc heterogeneous wireless sensor network architecture. We consider the situation when sensors are deployed in the surveillance area according to a uniform distribution perturbed by a Gaussian noise. We derive analytically the minimum detection range which guarantees an emerging structure in the network, namely the connectivity,...
