Abstract
A solution to the problem of sensor bias estimation is presented for a multiple target scenario with asynchronous sensors. Expectation maximisation is used to decouple the target state and sensor bias estimation problems by treating the target states as missing data. The approach is compared with the EX method, which solves the bias estimation problem by using differences between measurements from different sensors.
