Comparative Statistical Analysis of New Adaptive Filtering Techniques for Precise Indoor Local Positioning
This paper compares two different recursive tracking techniques for precisely localizing a mobile vehicle in an indoor harsh industrial environment. An Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF), the corresponding algorithms and mathematical models are presented and analyzed. Experimental range measurements generated from local positioning radar system are used to test the performance of these algorithms with respect to position and velocity root mean square errors. True and estimated trajectories of the mobile vehicle with associated means and error covariances are illustrated with the number of samples required in each case.
