摘要

This paper deals with fusion of estimates of linear dynamic systems. A new fusion filter is proposed that uses optimal mean square combination of arbitrary number of local estimates. The proposed filter is tested and results produced are very close to optimal Kalman filter estimate. The main advantage of proposed filter is its parallel architecture that allows simultaneous processing of individual sensor measurements compared with optimal Kalman estimate requiring all measurements for estimation. The proposed filter is equally suited for centralized, hierarchical or distributed architectures and can produce well-timed results, eliminating the drawback of centralized data fusion systems.
