Abstract
In this paper,we present an adaptive extended Kalman filter(AEKF) algorithm aiming at the issues such as divergence,slow convergence and low precision of filters in passive targets tracking.The algorithm can estimate the statistics features of the virtual state noise on-line and compensate the error caused by model’s non-linearization and reduce the error in observation for systems.Simulation results show that the algorithm improves the filtering convergence rate and the accuracy,and is better than the original extended Kalman filter(EKF).
