Abstract
Two fusion formulas with scalar and matrix weights are presented. The statistical relationship between them is established. They are compared on the multi-sensor Kalman filtering problem. The basic equation for cross-covariance of the local Kalman estimates being the key quantity for distributed fusion is derived. Examples demonstrating the desirable accuracy of the proposed fusion filters are given.
