Methods and systems for producing data describing target measurements using a processor in a system having at least one on-board sensor on a vehicle. The method includes obtaining data from an on-board sensor 304, obtaining data from a sensor off-board the vehicle, approximating a target alignment error between the on-board and off-board sensor data 312, receiving target alignment error data derived from second data obtained from the on-board and off-board sensors, estimating a bias 316 using the received target alignment error data and correcting the approximated target alignment error using the bias, and performing 320 a data fusion process on the obtained off-board sensor data and the obtained on-board sensor data using the approximated target alignment error to produce target measurement data. A target alignment error may be approximated for a plurality of on-board/off-board track pairs using track data from a plurality of pairs of on-board and off-board sensors. |
