An identifying method of the materiel using multi-layered compound data fusion strategy

In allusion to the features of the identifying material, according to the modern data fusion theory, the paper presents an automatic identifying method of the materiel using the multi-sensor and multi-layered compound data fusion strategy based on the field bus and the analyzing physical attribute of the materiel. First utilizing the wavelet analysis method, the data that comes from the field sensors is done with the pretreatments that include anti-jamming and noise-reinoving and property-distilling, and also by the WorldFIP field bus, the data is transmitted to the center data fusion unit which contains several model fusion methods and enters into the suitable fusion arithmetic to complete the fusion separately and automatically on the basis of the type of the data, and then the outputting information comes into the expert Arbitration unit to realize the precise identification of materiel. The experiment results show that the method is feasible and efficient.
