Abstract EN
We investigate the problem of target tracking using a wireless sensor network with asynchronous sensors.
To study the impact of sensor clock imperfection on target tracking in practical situations, we build a testbed and collect data from an outdoor experiment.
After analyzing the collected data, we find that the TDOA (time-difference-of-arrival) and FDOA (frequency-difference-of-arrival) measurements have notable bias, which is caused by asynchronous sensors or more precisely by the sensor clock drift.
Based on the model of clock drift, the measurement bias and the target position are integrated into a state-space model.
Both can be estimated in the framework of the extend Kalman filter.
In some circumstance, the target trajectory is tracked successfully.
