摘要：

A procedure to fuse state estimates of the same target obtained from different sensors is presented. This procedure accounts for the fact that such estimates have dependent errors due to the common process noise. An example in which estimates obtained from two alpha - beta filters were fused indicates that the uncertainty area corresponding to the fused estimates is about 70% of the single-sensor uncertainty area over a wide range of the process noise variance. This is in contrast to the 50% obtained if the dependence is not accounted for.
