Unscented Kalman Filter Tutorial - University of South ...
cse.sc.eduThe Unscented Kalman Filter belongs to a bigger class of filters called Sigma-Point Kalman Filters or Linear Regression Kalman Filters, which are using the statistical linearization technique [1, 5]. This technique is used to linearize a nonlinear function of a random variable through a linear

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-
