New approach to online optimal estimation of multisensor biases

The paper presents a new approach to multiple sensor bias estimation. It is applied to a practical example: correcting radar biases for ATC applications. A novel procedure to organise and process measurements is proposed and compared with classical approaches, which are shown to achieve inferior performance. It is shown how the exploitation of all available information allowed by the proposed data arrangement improves the accuracy of estimates. Besides, efficient implementations are developed and a cost-benefit analysis of the main alternatives for this problem is presented in the results.
