An Introduction to the Kalman Filter - Computer Science
www.cs.unc.eduJul 24, 2006 · Kalman filter has been the subject of extensive research and application, particularly in the area of autonomous or assisted navigation. A very ÒfriendlyÓ introduction to the general idea of the Kalman filter can be found in Chapter 1 of [Maybeck79], while a more complete introductory discussion can be found in [Sorenson70], which also ...
The Unscented Kalman Filter for Nonlinear Estimation
groups.seas.harvard.eduintroduces an improvement, the Unscented Kalman Filter (UKF), proposed by Julier and Uhlman [5]. A central and vital operation performedin the Kalman Filter is the prop-agation of a Gaussian random variable (GRV) through the system dynamics. In the EKF, the state distribution is ap-proximated by a GRV, which is then propagated analyti-
