Kalman filter update with multiple measurements

Nov 30, 2009 2 Replies

Hi.



I have a system which I track using a Kalman filter. In the update step I, however, have multiple measurements from different sensors available with their respective covariances. Any input on how to take advantage of this in a Kalman filter?



Thanks in advance.


If this is the usual Kalman construction and you just follow the normal recipe for it, you should "automatically" get the right weighting for your various sensors -- even if you have redundant sensors each with a different linear combination of the the variables you're measuring.

BTW: Telling us what you're up to may help get your more directed answers.
