The Unscented Particle Filter

THE UNSCENTED KALMAN FILTER - Pudn.com
7.6 THE UNSCENTED PARTICLE FILTER 259. The effectiveness of this approximation depends on how close the proposal distribution is to the true posterior distribution. If there is not sufficient overlap, only a few particles will have significant importance ... Retrieve Content

Unscented Kalman Filter Demo - YouTube
This is a demo of a simple Unscented Kalman Filter tracking a simulated target from a radar station. The estimated state includes [x, y, angle, rotational velocity, translational velocity], while the only (very noisy) observations coming in from the "radar station" are [range, bearing ...
