Multi-sensor data fusion in a distributed environment; architectural solutions

The human operator observing the real world is confronted with a huge amount of data from multiple sensors observing that world. Multi-sensor data fusion (MSDF) is one of the emerging fields in advanced information processing, concerned with fusing sensor data from these multiple sensors. Automated MSDF can help the operator by processing sensor...

A method and measures to evaluate trackers for air traffic control

The general setup of the evaluation of a radar tracking algorithm in a civil ATC-system has been considered from an operational point of view. Both the present and the potential future use of trackdate has been taken in account. The result is a method to evaluate trackers for ATC on the basis of live-traffic data, under the assumption that a...

Comparison of a jump-diffusion tracker with a Kalman tracker: an evaluation with emphasis on air traffic control

A sophisticated starting point for a probabilistic approach to the radar tracking problem is a Markov jump-diffusion model for the aircraft dynamics, its control and the radar measurements. From nonlinear filtering theory, a closed form description of the evolution of the conditional distribution of this Markov process can be obtained. This jump...

Image data security in the concept of the agricultural real time imaging satellite system (artiss)

The study on image data security is directed to the requirement for exclusive access to satellite imagery in the concept of the Agricultiiral Real Time Imaging Satellite System (ARTISS). The security assessment indicates that user survey requests are handled confidentially and it shows the access vulnerability of the transmission of image data...
