A Robust Adaptive Unscented Kalman Filter for Floating Doppler Wind-LiDAR Motion Correction
نویسندگان
چکیده
This study presents a new method for correcting the six degrees of freedom motion-induced error in ZephIR 300 floating Doppler Wind-LiDAR-derived data, based on Robust Adaptive Unscented Kalman Filter. The filter takes advantage known Wind-LiDAR (FDWL) dynamics, velocity–azimuth display algorithm, and wind model describing LiDAR-retrieved vector without motion influence. estimates corrected by adapting itself to different atmospheric scenarios, estimating covariance matrices related noise processes. measured turbulence intensity FDWL (with correction) was compared against reference fixed LiDAR over 25-day period at “El Pont del Petroli”, Barcelona. After correction, apparent greatly reduced, statistical indicators showed overall improvement. Thus, Mean Difference improved from ?1.70% (uncorrected) 0.36% (corrected), Root Square Error (RMSE) 2.01% 0.86%, coefficient determination 0.85 0.93.

Doppler and bearing tracking using fuzzy adaptive unscented Kalman filter
The topic of Doppler and Bearing Tracking (DBT) problem is to achieve a target trajectory using the Doppler and Bearing measurements. The difficulty of DBT problem comes from the nonlinearity terms exposed in the measurement equations. Several techniques were studied to deal with this topic, such as the unscented Kalman filter. Nevertheless, the performance of the filter depends directly on the...
متن کاملA Hybrid Adaptive Unscented Kalman Filter Algorithm
In order to overcome the limitation of the traditional adaptive Unscented Kalman Filtering (UKF) algorithm in noise covariance estimation for statement and measurement, we propose a hybrid adaptive UKF algorithm based on combining Maximum a posteriori (MAP) criterion and Maximum likelihood (ML) criterion, in this paper. First, to prevent the actual noise covariance deviating from the true value...

We consider the problem of nonlinear filtering under the circumstance of unknown covariance statistic of the measurement noise. A novel adaptive unscented Kalman filter (UKF) integrating variational Bayesian methods and fuzzy logic techniques is proposed in this paper. It is called fuzzy adaptive variational Bayesian UKF (FAVBUKF). Firstly, the sufficient statistics of the measurement noise var...
