Analysis of data fusion architectures and techniques in the development of an A-SMGCS Surveillance prototype

* This work has been funded by the Spanish CICYT contracts: TIC2002-04491-C01/02 and CAM (07T/0034/2003 1) Abstract The work presented here addresses a key aspect of the data fusion process carried out by A-SMGCS Surveillance, needed to take maximum advantage from the simultaneous use of diverse detection and measurement technologies with complementary characteristics. The core function, Surveillance, must collect and fuse information from available sensors and information systems. The accuracy, coverage and refreshment rate in all-weather conditions must be high enough to satisfy the requirements. In a real application, this function will be constrained to deal with the specifications of output sensor data, formats, accuracies, etc. for the available sensors in the airport. In this work, we present a comparative analysis of data fusion architectures and some alternative algorithms to develop a real system deployed in Spanish airports, analyzing the capabilities and problems of different types of solutions
