A New Bias Pseudo-Measurement Method for Distributed Sensor Bias Estimation

To deal with the problem of sensor registration in distributed sensors, a common method is to construct pseudo-measurements only related to the bias vector, and then estimate the bias through these pseudo-measurements. Consider the scene of limited communication, a new method to construct the bias pseudo-measurement only by operating the local tracks, covariances, and the equivalent bias measurement matrices is proposed in this paper. Compared with the existing methods, the proposed method can save about 36.4% of the communication cost with other performance unchanged in the system exemplified in this paper.
