Under complex conditions, the fusion of some special data will no longer satisfy the error characteristics hypothesis of the Kalman filter algorithm. Fuzzy Kalman filter adaptively adjusts the noise covariance matrix by introducing fuzzy control rules, so that the noise in the model can get closer to the real noise level. Based on the analysis of the error characteristics, this paper proposes fuzzy Kalman filtering method based on different error sources, using different inference rules and covariance matrix adjustment strategy. The simulation experiment proves the rationality and effectiveness of the method.
Key words: fuzzy Kalman filter; data fusion; noise covariance; target tracking
