Distributed and Layered Sensing

Abstract: One can easily envision future military operations and emerging civilian requirements (e.g. intelligent unmanned vehicles for urban warfare, intelligent manufacturing plants) that will be both complex and stressing and will demand innovative sensors and sensor configurations. The goal of our research into Distributed and Layered Sensing is to develop a cost effective and extendable approach for providing surveillance for a variety of applications in dynamically changing military and civilian environments.

“…This is particularly relevant in our rangeonly sensing context, when initializing the state of a newly observed target from a bistatic measurement at the single receiver node. Indeed, the lack of any angle information requires the prior pdf of the potential target state, in particular the component related to the 3D position, to cover a large volume, potentially the entire focaloid induced by the bistatic range measurement as well as transmitter and receiver positions; 13 clearly, the resulting prior pdf cannot be reliable represented by a small number of particles. Needless to say, both an inaccurate prior distribution choice and its rough representation can propagate via the target dynamics over time, degrading the overall tracking performance.…”

“…This effect is generally addressed through resampling, which however might cause particle impoverishment, that is, a reduction of particle diversity [66]. 13 A focaloid is a shell bounded by two confocal ellipsoids; it reduces to a spherical shell when transmitter and receiver are colocated.…”
