Abstract
In the actual course of target tracking, the observation noise is changing at any time because of the impact of the distance between the target and the radar and other reasons. However, the observation noise covariance is changeless in the normal Kalman filter, so the tracking result is not perfect inevitably. In order to solve this problem, a novel algorithm is presented to adjust the observation noise covariance adaptively based on the two results of Kalman filter with different sample times. The simulation experiments show that the proposed algorithm improves the result of tracking.
