Design of multi-source and multi-dimension information fusion of avionics system

In the future, the war will be developed from platform-centred form to network-centred one, which will integrate the information from the equipment of land, sea, air and space. In this countermeasure environment, the source and type of information will be various and the electromagnetic interference will be very complex. To adapt the cooperative combat mode in NCW, the avionic system of airborne should integrate the information which is not only from onboard but also from off-board sensors in the ground, warship, airborne and satellite. Then, an information fusion technology is needed to deal with the multi-platform information by associating, analyzing, processing, optimizing and reasoning. After that, the globe and unified battlefield situation can be obtained, and cooperative attack and defense would come into being. This paper first analyzes the military requirements of information fusion technology used for future war, and then describes the composition, functions and architecture of Multi-Source and MultiDimension Information Fusion System (MSMDIFS) used in avionics. The configuration and the realization of MSMDIFS are discussed in detail. At last, several key techniques involved in the system are presented and the results of the closed loop dynamic tests in laboratory are given.
